DETAILED DESCRIPTION

The present disclosure is directed to textiles or combinations of textiles and other materials (e.g., shaped components, films, second textiles, yarns or fibers), where one or more of the textiles or other materials include a low processing temperature composition, and one or more of the textiles or other materials include a high processing temperature composition. In some aspects, a single textile includes both the low and high processing temperature compositions. The present disclosure is also directed to methods of thermoforming on a molding surface the textile alone or in combination with one or more other materials to re-shape the textile, to affix the one or more other materials to the textile using re-flown polymeric materials, or both. The thermoforming process involves placing at least a portion of a textile on a molding surface, and, while the textile remains in contact with the molding surface, increasing the temperature of the entire textile to a first temperature, and then decreasing the temperature of the entire textile to a second temperature. The first temperature is a temperature above the melting point of the low processing temperature composition, but is below the below at least one of: 1) the creep relaxation temperature T_(cr); 2) the heat deflection temperature T_(hd); or 3) the Vicat softening temperature T_(vs) of the high processing temperature polymeric composition. Thus, using the disclosed process, the portions of the textile and/or one or more materials which comprise the low processing temperature composition will melt, re-flow and then re-solidify into a new shape or conformation, while the portions formed high processing temperature composition will retain their original shape or conformation. Forming first fibers and/or yarns from the low processing temperature composition and using these fibers and/or yarns to construct textiles, such as woven textiles, knit textile, non-woven textiles, braided textiles, etc.) is a particularly efficient and effective way to incorporate these thermoforming processes low processing temperature composition. For example, use of the disclosed textiles and processes make it possible to use only a single textile to produce a thermoformed article which includes integrally formed areas with attributes ranging from a conventional textile to a solid molded polymeric material using only a single thermoforming process. Creating yarns and or fibers which work well in the disclosed process while also producing finished articles with desirable attributes was found to require the use of low processing temperature compositions having a balance of properties, which are disclosed here.

In traditional forming of an article including articles of wear, transitions from a first region of functionality to a second region of functionality can be accomplished through a change in material imparting the functionality. This transition from a first material having a first functional description to a second material having a different functional description can introduce limitations to the final article. For example, in the context of a shoe, a transition from a sole to an upper occurs near a biteline of the shoe. This transition can be referred to as a hard-to-soft transition as the sole generally has a relatively rigid response to foot movement and the upper has a relatively generally non-rigid response to the foot movement. Other such hard-to-soft transitions can be present in other locations on a shoe, depending upon the design and methods of construction used. At this transition, the wearer of the shoe can experience discomfort as portions of the foot on one side of the transition are allowed to move in a different (e.g., more free) manner than portions of the foot on the other side of the transition. This abrupt change (e.g., hard-to-soft transition) in the allowed freedom of movement of the wearer's foot can affect perceived performance and feel of the shoe. To limit the impact of the hard-to-soft transition, manufacturers can insert multiple layers of materials or otherwise mechanically manipulate the transition region to mask the change. Each of these alterations can insert complexity, additional processing steps, and/or materials that can further influence efficiencies, costs, and weight of the shoe.

As such, aspects contemplated herein allow for an integrally formed article portion having a transition from a first functional region to a second functional region that is engineered into and during the formation of the regions. For example, a manipulation of materials and techniques, such as knitting stitches, can be implemented to allow for a gradient from the first functional region to the second functional region. Relating this back to the hard-to-soft transition of a shoe, it is contemplated that a first functional region (e.g., a sole region) of the shoe can be formed (e.g., knit) with a first type of material (e.g., low processing temperature polymeric composition described below) and the second functional region (e.g., an upper portion) of the shoe is formed (e.g., knit) with a different material (e.g., high processing temperature polymeric composition described below). Additionally or alternatively, the sole region of the shoe is knit with a first type of stitch and the upper portion of the shoe is knit with a second type of stitch. Further, in this example, the transition from the first functional region (e.g., the sole region) to the second functional region (e.g., the upper region) can include one or more transitions zones where knitting techniques (e.g., stitch selection, layer manipulation) and/or materials are blended in defined manners to integrally form a more natural transition from the first functional region to the second functional region during the manufacturing of the region. This integral transition between functional zones can positively influence the perceived performance and/or feel of the shoe to a wearer in an exemplary aspect.

That is, the knitting process substantially forms the various features and structures of the knit article without the need for significant additional manufacturing steps or processes. Although portions of knit article can be joined to each other (e.g., edges of the knit article being joined together, as at seam) following the knitting process, the knit article remains formed of unitary knit construction because it is formed as a one-piece knit element. In various aspects, the knit article can further comprise other elements (e.g., a tongue, a strobel, a lace, a heel counter, logos, trademarks, placards) that can be added following the knitting process.

The knit textile can incorporate various types and combinations of stitches and yarns. With regard to stitches, the knit textile can have one type of stitch in one area of the knit textile and another type of stitch in another area of the knit textile. Depending upon the types and combinations of stitches utilized, areas of the knit textile can have, for example, a plain knit structure, a mesh knit structure, or a rib knit structure. The different types of stitches may affect the physical properties of the knit textile, including aesthetics, stretch, thickness, air permeability, and abrasion-resistance. That is, the different types of stitches may impart different properties to different areas of knit textile. With regard to yarns, the knit textile may have one type of yarn in one area of the knit textile and another type of yarn in another area of the knit textile, e.g., a yarn comprising a low processing temperature polymeric composition in one area of the knit textile and a yarn comprising a high processing temperature polymeric composition in another area of the knit textile. Depending upon various design criteria, the knit textile can incorporate yarns with different deniers, materials (e.g., cotton, elastane, polyester, rayon, wool, and nylon), and degrees of twist, for example. The different types of yarns may affect the physical properties of the knit textile, including aesthetics, stretch, thickness, air permeability, and abrasion-resistance. That is, the different types of yarns may impart different properties to different areas of the knit textile. By combining various types and combinations of stitches and yarns, each area knit article can have specific properties that enhance the comfort, durability, and performance of the knit textile as required by its use in an article of footwear, article of apparel, or article of sporting equipment.

The knit textile can be prepared by a variety suitable processes. For example, a flat knitting process can be utilized to manufacture the knit textile.

The knit upper for an article of footwear further includes a second yarn comprising a high processing temperature polymeric composition. The first and second yarns at least partly form a plurality of interconnected courses in at least one knit layer of the knit upper for an article of footwear, the at least one knit layer having at least a first zone, a second zone, and a third zone, the second zone positioned between the first and third zones, wherein the first zone comprises an increased concentration of the second yarn compared to the second zone, and wherein the third zone comprises an increased concentration of the first yarn compared to the second zone. In some examples this structure can form an outer surface of an article, where the first, second and third zones each form a portion of the outer surface.

In certain aspects, a knit upper for an article of footwear is provided comprising a melted yarn component comprising a low processing temperature polymeric composition. The melted yarn component is thermoformed from a first state as a first yarn into a second state as the melted yarn component. The knit upper for an article of footwear also includes a second yarn including a high processing temperature polymeric composition. The melted yarn component and the second yarn at least partly form a surface having at least a first zone, a second zone, and a third zone, with the second zone positioned between the first and third zones. The first zone includes a higher concentration of the second yarn compared to the second zone, and the third zone includes a higher concentration of the melted yarn component compared to the second zone. In some examples this structure can form an outer surface of an article, where the first, second and third zones each form a portion of the outer surface.

In some aspects, the article of wear is an article of footwear, which include, but are not limited to, such articles as shoes. Articles of footwear generally include an upper and a sole structure. The upper provides a covering for the foot that comfortably receives and securely positions the foot with respect to the sole structure. Moreover, the upper generally provides protection for the foot. The sole structure can provide various kinds of support, cushioning and shock absorption. The sole structure is secured to a lower portion of the upper and is generally positioned between the foot and the ground. In addition to attenuating ground reaction forces (that is, providing cushioning) during walking, running, and other ambulatory activities, the sole structure can influence foot motions (for example, by resisting pronation), impart stability, and provide traction, for example. Accordingly, the upper and the sole structure operate cooperatively to provide a comfortable structure that is suited for a wide variety of athletic activities.

An upper forms a structure that that provides a covering for some or all of a wearer's foot and positions that foot relative to a sole structure of that shoe. The upper forms a void on the interior of the footwear for receiving the foot. The void has the general shape of the foot, and access to the void is provided at an ankle opening. In certain aspects, the upper extends over instep and toe areas of the foot, along medial and lateral sides of the foot, and around the heel area of the foot. The upper can have any design, shape, size and/or color. For example, in certain aspects, e.g., if an article is a basketball shoe, then the upper can be a high top upper that is shaped to provide high support on an ankle. Alternatively, in certain aspects, e.g., if an article is a running shoe, then the upper can be a low top upper.

The upper can also incorporate a lacing system to adjust fit of the footwear, as well as permit entry and removal of the foot from the void within the upper. A lacing system often is incorporated into the upper to selectively change the size of the ankle opening and to permit the wearer to modify certain dimensions of the upper, particularly girth, to accommodate feet with varying proportions. In addition, the upper can include a tongue that extends under the lacing system to enhance the comfort of the footwear (e.g., to modulate pressure applied to the foot by the laces), and the upper also can include a heel counter to limit or control movement of the heel. In addition, the upper can include a tongue that extends under the lacing system to enhance adjustability and comfort of the footwear, and the upper can incorporate a heel counter.

In some aspects, a sole structure can one or more components or layers, which can individually or collectively provide an article of footwear with a number of attributes, such as support, rigidity, flexibility, stability, cushioning, comfort, reduced weight, or other attributes. In some aspects, a sole structure can comprise layers referred to as an insole, a midsole, and an outsole. In some aspects, however, one or more of these components can be omitted. In certain aspects, a sole can optionally comprise a sole plate. In some aspects, the sole structure comprises at an outsole component that includes an exterior major surface, which can be exposed and ground-contacting, and an interior major surface. In a further aspect, the sole structure can further comprise a midsole component that can be attached to the upper along the entire length of the upper. When present, the midsole forms the middle layer of the sole structure and serves a variety of purposes that include controlling foot motions and attenuating impact forces.

The midsole, which may be attached to the upper along the entire length of the upper, forms the middle layer of the sole structure and serves a variety of purposes that include controlling foot motions and attenuating impact forces. Many midsole configurations are primarily formed from a resilient polymer foam material, such as polyurethane (PU) or ethylene-vinyl acetate (EVA), that extends throughout the length and width of the footwear. The midsole can also incorporate plates, moderators, fluid-filled chambers, and/or other elements that further attenuate forces, influence the motions of the foot, and/or impart stability, for example.

The outsole forms the ground-contacting element of footwear and is usually fashioned from a durable, wear-resistant material that includes texturing or other features to improve traction. The outsole can be fashioned from a durable and wear-resistant material (for example, rubber) that includes texturing to improve traction. The outsole can optionally further comprise cleats.

In some aspects, an article of footwear can further comprise a sock liner, that is a thin member located within the upper and adjacent the plantar (lower) surface of the foot to enhance footwear comfort, e.g., to wick away moisture and provide a soft, comfortable feel. In some aspects, the sockliner can be formed of a foam material such as a polyurethane foam, foamed rubber or ethylene vinyl acetate. In certain aspects, the sockliner is not glued or otherwise attached to the sole structure. Alternatively, the sockliner can be attached to the sole structure.

In certain aspects, a knit upper for an article of footwear is provided comprising a plurality of interconnected courses. Each course of the plurality of interconnected courses includes a first yarn and a second yarn. The first yarn comprises a low processing temperature polymeric composition comprising one or more first thermoplastic polymers. The second yarn comprises a high processing temperature polymeric composition comprising one or more second thermoplastic polymers. The knit upper for an article of footwear also includes at least one knit layer including at least a first zone, a second zone, and a third zone, with the second zone positioned between the first and third zones. Each course of the plurality of interconnected courses extends through the first zone, the second zone, and the third zone, where the third zone has an increased concentration of the first yarn compared to the second zone. In addition, the knit upper for an article of footwear includes an anchor yarn that extends through at least a portion of the third zone. The anchor yarn includes an anchor yarn composition that includes one or more polymers. The anchor yarn exhibits an elongation that is less than an elongation of the first yarn.

Exemplary Aspects of Article of Sporting Equipment, Articles of Wear and Textiles

As discussed above, certain aspects are directed to one or more textiles that include fibers and/or yarns comprising the low processing temperature polymeric composition and the high processing temperature polymeric composition. In certain aspects, such textiles can form at least a portion of an article of sporting equipment or article of wear. In certain aspects, the disclosed textiles can form at least a portion of a component of an article of footwear. In certain aspects, the disclosed textiles can form at least a portion of a component of an article of sporting equipment. For example, the disclosed textiles can form at least a portion of an upper for a shoe, such as an athletic shoe.

Turning now to the figures, in particular, FIGS. 1A and 1B, an article of footwear 100 is depicted as one exemplary article of wear. While FIGS. 1A and 1B depict an article of footwear 100. While FIGS. 1A and 1B depict an article of footwear 100, it should be understood that other articles of wear are also contemplated by the present disclosure. The article of footwear 100 of FIGS. 1A and 1B generally can include a ground-facing outsole area 110, an ankle collar area 112, a lateral midfoot area 114 a, and a medial midfoot area 114 b, a toe box area 116, and a heel area 118. Further, the article of footwear 100 can include a plurality of eyestays 120, a vamp area 122, a tongue area 124, and a throat area 126. As shown in FIGS. 1A and 1B, article of footwear 100, is intended to be used with a right foot; however, it should be understood that the following discussion can equally apply to a mirror image of article of footwear 100 that is intended for use with a left foot.

The article of footwear 100 depicted in FIGS. 1A and 1B can include at least one textile 102 that at least partly forms a portion of the article of footwear 100. The textile 102 of the article of footwear 100 can include at least three separate textile zones, e.g., zones 104, 106, and 108, identifying specific functional areas of the article of footwear 100. In certain aspects, these specific functional areas are at least partly associated with the targeted incorporation of specific textile media in varying amounts, techniques, and combinations into these textile zones (illustrated as zones 104, 106, and 108 in FIGS. 1A and 1B). It should be understood that, while the textile 102 includes three specific functional areas, more than three functional areas are also contemplated.

In certain aspects, the textile zone 104 can exhibit a rigid or semi-rigid functionality suitable for use as a ground-facing outsole 110 for the article of footwear 100. Accordingly, in certain aspects, the textile zone 104 can be positioned to include at least a portion of a ground-facing outsole 110 of the article of footwear 100. In certain aspects, the targeted incorporation of the low processing temperature polymeric composition into the textile zone 104 of the textile 102, upon thermoforming, can at least partly provide the rigid or semi-rigid functionality for use as a ground-facing outsole 110. As used herein “thermoforming” refers to a process that can include the melting and/or deforming of the low processing temperature polymeric composition and/or one or more thermoplastic polymers and the subsequent cooling of the melted and/or deformed material to form a plaque or film, which can be rigid or semi-rigid. The thermoforming process is discussed in detail below.

Further, in aspects, another textile zone, such as, for example, textile zone 108, can exhibit flexibility and/or pliability to accommodate movements from a wearer. In certain aspects, the textile zone 108 can include the ankle collar area 112, the tongue area 124, and/or the throat area 126 of the article of footwear 100. In various aspects, the textile zone 108 can include a high processing temperature polymeric composition.

In certain aspects, another textile, such as, for example, zone 106, can be positioned between the textile zones 104 and 108. In certain aspects, the textile zone 106 can include at least a portion of the lateral midfoot region 114 a and/or the medial midfoot region 114 b on the article of footwear 100. In certain aspects, the textile zone 106 can include a combination of the low processing temperature polymeric composition from the textile zone 104 and the high processing temperature polymeric composition from the textile zone 108. In such aspects, this combination of textile media present in the textile zone 106 allows the textile zone 106 to function as a transition between the rigid or semi-rigid functionality of the textile zone 104 and the flexible pliable functionality of the textile zone 108, allowing for a more gradual transition from rigidness to flexibility of the textile 102.

Further, in such aspects, the textile zone 106 can exhibit rigidity or semi-rigidity to a lesser extent than the textile zone 104, but to a greater extent than the textile zone 108. Also, in the same or alternative aspects, the textile zone 106 can exhibit flexibility to a lesser extent than the textile zone 108, but to a greater extent than the textile zone 104.

Alternatively or additionally, the three textile zones 104, 106 and 108 can be at least partly located within a midfoot region, such as lateral midfoot region 114 a and/or medial midfoot region 114 b.

In certain aspects in the textile zone 106, the combination of the low processing temperature polymeric composition present in the textile zone 104 and the high processing temperature polymeric composition present in the textile zone 108, when exposed to the thermoforming process, can impart one or more structural properties to the article of footwear 100, such as semi-rigid support in the lateral and/or medial midfoot regions 114 a and 114 b, and/or three-dimensional shape or structure to one or more portions of the article of footwear 100.

In certain aspects, as can be seen in FIG. 1A, the textile zone 106 extends away from the textile zone 104 towards the eyestays 120. In such aspects, the combination of textile media comprising the low processing temperature polymeric composition and textile media comprising the high processing temperature polymeric composition can allow for the transferring of a force transmitted from the eyestays 120 or other lacing mechanisms into this combination of textile media present in the lateral and/or medial midfoot regions 114 a and 114 b. In certain aspects, for the successful transfer of the forces transmitted from the eyestays 120, the textile zone 104, and/or the low processing temperature polymeric composition present in the textile zone 104, can terminate to an area 128 that is a distance of at least about 0.5 cm, about 1.0 cm, or about 2.0 cm from the eyestays 120, and/or at least about 3, at least about 4, or at least about 5 needles below the eyestays 120, when the textile 102 is a knit textile formed on a commercial knitting machine. In such aspects, the flexible and pliable characteristics of the high processing temperature polymeric composition that is present in the zone 108 that is adjacent the eyestays 120 can facilitate in transferring forces transmitted from the eyestays 120 to the textile zone 106 and/or the low processing temperature polymeric composition present in the lateral and/or medial midfoot regions 114 a and 114 b.

In the aspect depicted in FIGS. 1A and 1B, the textile zone 106 is positioned in the toe box area 116 and the heel area 118. In such aspects, the combination of the low processing temperature polymeric composition and the high processing temperature polymeric composition can provide structure and/or support due to the rigidity provided by the thermoformed material. Further, the thermoformed material can provide abrasion resistance in the toe box area 116 and/or the heel area 118. In alternative aspects, the textile zone 104 can form at least a portion of the toe box area 116 and/or the heel area 118 for increased rigidity or increased abrasion resistance, since the textile zone 104 includes a greater amount, or alternative positioning (e.g., outer knit surface), of the low processing temperature polymeric composition than the textile zone 106.

FIG. 1C depicts an alternative aspect of an article of footwear 100 a. In such aspects, the article of footwear 100 a can generally include at least three types of textile zones: the textile zone 104 a, the textile zone 106 a, and the textile zone 108 a. In certain aspects, the textile zones 104 a, 106 a, and 108 a can have the same properties and parameters as the textile zones 104, 106, and 108, respectively, of the article of footwear 100 discussed above with reference to FIG. 1A.

In the aspect depicted in FIG. 1C, portions, e.g., portions 104 b and 104 c, of the textile zone 104 a can extend from an outsole area up through a midfoot area 115A and toward a plurality of eyestays 120 a. In such aspects, a rigid or semi-rigid functionality provided by the portions 104 b and 104 c extending from an outsole area through the midfoot area 115A to a plurality of eyestays 120 a can provide increased wearer stability in the midfoot area 115A. Further, in aspects, a force applied through one or more of the plurality of eyestays 120 a can at least partly be transferred onto the rigid or semi-rigid portions 104 b and 104 c extending through the midfoot area 115A, and into the rigid or semi-rigid textile zone 104 a present in an outsole area, providing increased support and comfort for a wearer.

In certain aspects, in addition to the thermoformed material providing structure, rigidity, strength, and/or support to one or more areas of the article of wear, the thermoformed material can provide a water-proof or water-resistant surface.

FIGS. 2A and 2B depict a shirt 200 as an exemplary article of apparel. The shirt 200 depicted in FIGS. 2A and 2B includes at least one textile 202 that at least partly forms a portion of the shirt 200. As best seen in FIG. 2B, the textile 202 can include three separate textile zones 204, 206 a-d, and 208, which can identify specific functional areas of the 200. In certain aspects, these specific functional areas are at least partly associated with the targeted incorporation of specific textile media in varying amounts and combinations into these textile zones 204, 206 a-d, and 208.

In certain aspects, the textile zone 204 can include a reinforced area such as an exterior-facing film or patch 210, which can, for example, provide abrasion resistance to an elbow region 212 of the shirt 200. In such aspects, the targeted integral incorporation of the low processing temperature polymeric composition into the textile zone 204 can at least partly form the patch 210, when the textile 202 is thermoformed, by melting or deforming the low processing temperature polymeric composition and subsequent cooling and solidifying of the melted material to form a patch 210.

In various aspects, the textile zone 208 can exhibit flexibility and/or pliability similar to a conventional shirt material. In such aspects, the textile zone 208 can include or solely include the high processing temperature polymeric composition. Further, in certain aspects, the textile zone 206 can at least partly provide a transition within the textile 202 from the rigid or semi-rigid patch 210 present in textile zone 204 to the flexible pliable portion present in the textile zone 208. In such aspects, the textile zones 206 a-d can include a combination of the low processing temperature polymeric composition present in the textile zone 204 and the high processing temperature polymeric composition present in the textile zone 208. While not shown in FIGS. 2A and 2B, the textile zones 206 b-d also provide a transition to a flexible pliable material, such as that present in the textile zone 208.

In certain aspects, like with the textile zone 106 of the textile 102 discussed above with reference to FIGS. 1A and 1B, this combination of the low processing temperature polymeric composition from textile zone 204 and the high processing temperature polymeric composition present from textile zone 208 can provide a seamless or integrated transition from the patch 210 to the flexible pliable portion found in textile zone 208 of the shirt 200.

While this exemplary description in FIGS. 2A and 2B of the textile zones 204, 206 a-d, and 208 relates to an elbow region of the article of apparel 200, it should be understood that the textile zones 204, 206 a-d, and 208 and associated properties can be applied to other areas of a shirt or other articles of apparel, such as a knee, thigh, hip, chest, and/or lower back region of an article of apparel, or to areas requiring reinforcement such as areas adjacent to a fastener, for example, a zipper, a button, a snap, a pull cord, and the like.

Turning now to FIG. 3, a plan view of a schematic textile 300 is provided. It should be understood that the textile 300 can be any type of textile known to one skilled in the art. A non-limiting list of textiles that are suitable for use in the articles of wear and methods disclosed herein includes knit textiles, woven textiles, non-woven textiles, and braided textiles.

Similar to the textile 102 of FIGS. 1A and 1B, and the textile 202 of FIGS. 2A and 2B, the textile 300 of FIG. 3 includes three types of textile zones. For example, the textile 300 includes a textile zone 302 that can include fibers and/or yarns comprising a low processing temperature polymeric composition, textile zones 306 a and 306 b that can include a high processing temperature polymeric composition, and textile zones 304 a and 304 b that can include a combination of fibers and/or yarns comprising the low processing temperature polymeric composition and fibers and/or yarns comprising the high processing temperature polymeric composition. In textile 300 of FIG. 3, the textile zones 304 a and 304 b can be positioned on either side of textile zone 302, while textile zones 306 a and 306 b can be positioned on the opposite sides of the textile zones 304 and 304 b, respectively.

In certain aspects, the fibers and/or yarns comprising the low processing temperature polymeric composition present in textile zone 302, when exposed to a thermoforming process, can impart a structural or functional property to the textile 300 that can be used in forming an article of wear. For example, the textile zone 302 can represent the textile zone 104 of the textile 102 of FIGS. 1A and 1B, which forms at least a portion of a ground-facing outsole 112. In aspects, the fibers and/or yarns comprising the high processing temperature polymeric composition present in 306 a and 306 b can impart flexibility or pliability to the textile 300, such as the textile zone 108 of the article of footwear 100 depicted in FIGS. 1A and 1B. Further, in various aspects, the textile zones 304 a and 304 b can include a combination of fibers and/or yarns comprising the low processing temperature polymeric composition present in the textile zone 302 and fibers and/or yarns comprising the high processing temperature polymeric composition present in the textile zones 306 a and 306 b to provide structural support and three-dimensional structure for a particular article of wear. Further, as discussed above, in certain aspects, this combination of fibers and/or yarns comprising the low processing temperature polymeric composition and fibers and/or yarns comprising the high processing temperature polymeric composition in the textiles zones 304 a and 304 b can provide an integrated transition between the rigid thermoformed material in textile zone 302 and the flexible pliable high processing temperature polymeric composition in textile zones 306 a and 306 b.

In one or more aspects, the textile zones 304 a and 304 b can include a plurality of subzones, such as subzones 305 a, 305 b, 305 c, and 305 d of the textile zone 304 a, which can include varying combinations and/or varied positioning of the fibers and/or yarns comprising the low processing temperature polymeric composition and fibers and/or yarns comprising the high processing temperature polymeric composition. In certain aspects, the subzone 305 a can include fibers and/or yarns comprising the low processing temperature polymeric composition but not fibers and/or yarns comprising the high processing temperature polymeric composition present in the textile zones 306 a and/or 306 b. In the same or alternative aspects, the subzone 305 d can include fibers and/or yarns comprising the high processing temperature polymeric composition but not fibers and/or yarns comprising the low processing temperature polymeric composition present in the textile zone 302.

It should be understood that, while only the subzones of the textile zone 304 a can be further described herein, such descriptions apply to subzones present in the textile zone 304 b. Further, it should be understood that, if in certain descriptions only a textile zone 304 a and/or 306 a is further discussed, such descriptions also apply to the textile zones 304 b and 306 b, respectively.

In certain aspects, based on the relative positioning of the fibers and/or yarns comprising the low processing temperature polymeric composition and the fibers and/or yarns comprising the high processing temperature polymeric composition in the textiles zones 302, 304 a, and 306 a the textile 300 can have varying concentrations of the low processing temperature polymeric composition and/or high processing temperature polymeric composition in these textile zones 302, 304 a, 306 a.

As used herein, the term “concentration” refers to a clustering or congregation in a specific volume. Thus, the term concentration includes measuring the amount (e.g., the weight in grams) of a material in a specified volume (e.g., cm³). For example, in a knit textile, a first portion of a single knit layer of a textile can have an increased concentration of a first yarn compared to a second portion of the textile by having more stitches (e.g., knit stitches, tuck stitches, and/or float stitches) of that first yarn than the second portion of equal size. In another example, in a non-woven textile, a first portion of the textile can have an increased concentration of a first fiber if that textile was formed with more of the first fiber (e.g., a weight in grams) than a second portion of equal size.

In aspects, the textile zone 302 can include an increased concentration of fibers and/or yarns comprising the low processing temperature polymeric composition compared to the textile zones 304 a and/or 306 a. For example, in such aspects, the textile zone 302 can have at least 5 wt % more fibers and/or yarn comprising the low processing temperature polymeric composition compared to the textile zones 304 a and/or 306 a. In another aspect, the textile zone 302 can have at least 10 wt % more fibers and/or yarn comprising the low processing temperature polymeric composition compared to the textile zones 304 a and/or 306 a. In one aspect, the textile zone 302 can have at least 25 wt % more fibers and/or yarn comprising the low processing temperature polymeric composition compared to the textile zones 304 a and/or 306 a.

In the same or alternative aspects, the textile zone 304 a can include an increased concentration of fibers and/or yarn comprising the low processing temperature polymeric composition compared to the textile zones 306 a. For example, in such aspects, the textile zone 304 a can have at least 5 wt % more fibers and/or yarn comprising the low processing temperature polymeric composition compared to the textile zone 306 a. In another aspect, the textile zone 304 a can have at least 10 wt % more fibers and/or yarn comprising the low processing temperature polymeric composition compared to the textile zone 306 a. In one aspect, the textile zone 304 a can have at least 25 wt % more fibers and/or yarn comprising the low processing temperature polymeric composition compared to the textile zone 306 a.

In various aspects, the textile zone 306 a can include an increased concentration of fibers and/or yarn comprising the high processing temperature polymeric composition compared to the textile zones 302 and 304 a. For example, in such aspects, the textile zone 306 a can have at least 5 wt % more fibers and/or yarn comprising the high processing temperature polymeric composition compared to the textile zones 302 and/or 304 a. In another aspect, the textile zone 306 a can have at least 10 wt % more fibers and/or yarns comprising the high processing temperature polymeric composition compared to the textile zones 302 and/or 304 a. In one aspect, the textile zone 306 a can have at least 25 wt % more fibers and/or yarn comprising the high processing temperature polymeric composition compared to the textile zones 302 and/or 304 a.

In certain aspects, the textile zone 304 a can include an increased concentration of fibers and/or yarn comprising the high processing temperature polymeric composition compared to the textile zone 302. For example, in such aspects, the textile zone 304 a can have at least 5 wt % more fibers and/or yarn comprising the high processing temperature polymeric composition compared to the textile zone 302. In another aspect, the textile zone 304 a can have at least 10 wt % more fibers and/or yarn comprising the high processing temperature polymeric composition compared to the textile zone 302. In one aspect, the textile zone 304 a can have at least 25 wt % more fibers and/or yarn comprising the high processing temperature polymeric composition compared to the textile zones 302.

FIGS. 4A-4D schematically depict exemplary cross-sections of the textile zones 302, 304 a, and 306 a of the textile 300. Generally, FIG. 4A depicts an exemplary cross-section from the textile zone 306 a and further illustrates how, in certain aspects, this portion of the textile zone 306 a includes fibers and/or yarns comprising the high processing temperature polymeric composition but does not include fibers and/or yarn comprising the low processing temperature polymeric composition that is present in the textile zone 302. FIG. 4B depicts an exemplary cross-section of the textile zone 302 and also illustrates how, in various aspects, this portion of the textile zone 302 includes fibers and/or yarns comprising the low processing temperature polymeric composition but does not include fibers and/or yarns comprising the high processing temperature polymeric composition that is present in the textile zone 306 a. FIGS. 4C and 4D depict two exemplary cross-sections from the textile zone 304 a, and further illustrate how in these exemplary portions of the textile zone 304 a both fibers and/or yarns comprising the low processing temperature polymeric composition and fibers and/or yarns comprising the high processing temperature polymeric composition is present.

The cross-sections depicted in FIGS. 4A-4D will now be described from the perspective of the textile 300 being a knit textile. Various processes for forming a knit textile and the types of yarns that can be used are discussed in detail below. It is contemplated that a variety of knitting techniques can be implemented to achieve a described result. For example, in some aspects, a “knit stitch” can be substituted with a purl stitch to achieve a comparable result having a different aesthetic and/or texture. For purposes of simplicity herein, a “knit stitch” will be discussed while it is contemplated that a functional equivalent could be substituted. Similarly, a “tuck stitch” can be discussed in specific aspects, but it is also contemplated that alternative stitch techniques can be implemented to achieve a comparable result. Although a relatively simple knit structure is depicted and discussed, numerous warp knit and weft knit structures can be formed through flat knitting, wide tube circular knitting, narrow tube circular knit jacquard, single knit circular knit jacquard, double knit circular knit jacquard, double needle bar raschel, warp knit jacquard, and tricot for example.

It should be understood that the cross-sections depicted in FIGS. 4A-4D are schematic and each cross-section is organized into various segments to highlight potential knit structures that can be present. The potential knitting structures that can be present in the various segments of these cross-sections are described first.

FIGS. 5A-5J depict exemplary potential knitting structures that can be present in the various segments of the cross-sections depicted in FIGS. 4A-4D. FIG. 5A depicts a knit stitch (or sometimes referred to as a Jersey stitch) structure 502 formed from a back needle bed 504. It should be understood that the row of small circles associated with the back needle bed 504, represents needles (e.g., a needle 505) of the back needle bed 504, in accordance with traditional stitch schematics. Further, the same is true for a front needle bed, e.g., the front needle bed 508 depicted in FIG. 5B; that is, that the row of small circles associated with the front needle bed 508 represent needles (e.g., a needle 507) in the front needle bed 508.

FIG. 5B depicts a knit stitch structure 506 formed from a front needle bed 508. FIG. 5C depicts a float and tuck stitch structure 510, with tuck stitches that are formed by a front needle bed 512 and a back needle bed 514. FIG. 5D depicts another float and tuck stitch structure 516, with tuck stitches formed by a front needle bed 518 and a back needle bed 520. FIG. 5E depicts a float stitch structure 522. FIG. 5F depicts a knit and tuck stitch structure 524 having knit stitches 524 a formed by a back needle bed 528 and tuck stitches 524 b formed by a front needle bed 526. FIG. 5G depicts a knit and float stitch structure 530, with the knit stitches formed on a front needle bed 532. FIG. 5H depicts a knit and float stitch structure 534, with the knit stitches formed a back needle bed 536. FIG. 5I depicts a tuck and float knit structure 538, with the tuck stitches formed by a front needle bed 540. FIG. 5J depicts a tuck and float knit structure 542, with the tuck stitches formed by a back needle bed 544.

Returning now to the cross-sections 4A-4D of the textile 300. Generally, the cross-sections depicted 4A-4D are structured similarly, which is due to the primary structure of the knit textile. For example, in aspects, there is tubular knit structure that includes a knit structure formed primarily from a back needle bed (such as the knit structure 502 depicted in FIG. 5A) and a knit structure primarily formed on a front needle bed (such as the knit structure 506 depicted in FIG. 5B). Further, in such aspects, this tubular knit structure is connected via one or more tuck and float stitch structures, with tuck stitches formed from a back needle bed and a front needle bed (such as the tuck and float stitch structures 510 and 516 depicted in FIGS. 5C and 5D, respectively).

This connected tubular knit structure is schematically depicted in the three horizontal rows highlighted in the cross-sections depicted 4A-4D. For example, FIG. 4A depicts a cross-section 402 of the textile zone 306 a of FIG. 3 that includes the high processing temperature polymeric composition.

The cross-section 402 of FIG. 4A schematically depicts a top segment 404, a middle segment 406, and a bottom segment 408. The top segment 404 and the bottom segment 408 denote the knit structures for forming the tubular knit structure, while the middle segment 406 denotes the tuck and float stitch structures to connect the tubular knit structure together. Thus, in certain aspects, the top segment 404 can include one or more of the knitting structures 502 and 524 depicted in FIGS. 5A and 5F, respectively. The bottom segment 408 can include the knitting structure 506 depicted in FIG. 5B. The middle segment 406 can include one or more of the knit structures 510 and 516 depicted in FIGS. 5C and 5D, respectively.

FIG. 4B depicts a cross-section 410 of the textile zone 302 that includes yarn comprising the low processing temperature polymeric composition. The cross-section 410 includes a top segment 412, a middle segment 414, and a bottom segment 416, which can include the same knit structures identified above with respect to the top segment 404, the middle segment 406, and the bottom segment 408 of the cross-section 402 of FIG. 4A.

In certain aspects, it can be desirable to bulk up the low processing temperature polymeric composition in the textile zone 302 in order to provide a desired thickness and rigidity to the thermoformed textile zone 302, e.g., to form a ground-facing outsole of an article of footwear. In such aspects, the textile zone 302 can include repeat stitches to increase the concentration of the yarn comprising the low processing temperature polymeric composition relative to other textile zones, e.g., the textile zones 304 a and/or 306 a. In certain aspects, repeat stitches can be provided, for example, by including multiple stitch structures in any or all of the top segment 412, middle segment 414, and bottom segment 416 of the cross-section 410. In one example, multiple overlapping tuck and float stitch structures (such as the structures depicted in FIGS. 5C, 5D, 5I, and 5J) can be provided in the middle segment 414 of the cross-section 410.

In certain aspects, in regions of the textile 300 that include a substantial amount of yarn comprising the low processing temperature polymeric composition, e.g., the textile zone 302, an anchor yarn 413 can be provided in the textile 300 to help restrict the flow of the melted low processing temperature polymeric composition and/or to provide some flexibility to the thermoformed material. In the cross-section 410 depicted in FIG. 41, the anchor yarn 413 is depicted as being present in the middle segment 414 between the top and bottom segments 412 and 416, respectively. In such aspects, this positioning of the anchor yarn 413 can result in the embedding or the encapsulation of the anchor yarn 413 by the low processing temperature polymeric composition upon thermoforming of the textile 300.

While the anchor yarn 413 in FIG. 4B is depicted as a straight line it should be understood that this is a schematic representation of the anchor yarn 413 and is not meant to specify any particular type of knit structure. For example, the anchor yarn 413 can be present in the textile 300 as many different types of knit structure, such as one or more of structures depicted in FIGS. 5E and 5G-J. In certain aspects, the stitch selection for the anchor yarn 413 can depend upon the desired resistance to elongation of the material through which the anchor yarn 413 extends. For example, an anchor yarn stitch which floats five needles between tuck or knit stitches would provide a greater resistance to stretch to the material through which the anchor yarn 413 extends compared to an anchor yarn stitch which only floats 2 or 3 needles between tuck or knit stitches. In such an example, the differing resistance to elongation between the length of the float is a result of non-linear portions (e.g., stitch loops) that are more prone to elongation than linear segments, which results in different amounts of resistance to elongation.

In certain aspects, when the anchor yarn 413 is present as one or more of the knit structures depicted in FIGS. 5G-J, the anchor yarn 413 extends as a float stitch along at least two, at least three, at least four, or at least five adjacent loops of the yarn comprising the low processing temperature polymeric composition, since the yarn comprising the low processing temperature polymeric composition is also present as one or more of the knit structures of FIGS. 5A and 5B. Further in certain aspects, the anchor yarn 413 can extend as a float stitch along at least two, at least three, at least four, or at least five adjacent loops of the yarn comprising the low processing temperature polymeric composition and also can form at least a portion of a tuck stitch and/or a knit stitch with the yarn comprising the low processing temperature polymeric composition. In such aspects, a length between tuck stitches or knit stitches is at least partly formed with the yarn comprising the low processing temperature polymeric composition and the anchor yarn, the anchor yarn 413 can extend at least two, at least three, at least four, or at least five adjacent loops of the yarn comprising the low processing temperature polymeric composition. In the same or alternative aspects, the anchor yarn 413 can be stitched, e.g., tuck stitch or knit stitch, at loops spaced apart an amount represented by needle count of a common needle bed of within 50% or within 25% of the gauge of a knit machine used to form at least a portion of the textile 300.

FIGS. 4C and 4D depict cross-sections of the textile zone 304 a and portions of the textile zones 302 and 306 a. For example, the cross-section 418 of FIG. 4C includes a portion 422 that corresponds to the textile zone 302, and a portion 420 that corresponds to the textile zone 306 a. The portions 424 a, 424 b, 424 c, and 424 d correspond to the subzones 305 a, 305 b, 305 c, and 305 d, respectively, of the textile zone 304 a of the textile 300. The cross sections of FIGS. 4C-4E are simplified schematically; however, it is contemplated that one or more zones and/or portions of the cross sections can include a variety of fibers and/or yarns in different configurations and concentrations. For example, textile zone 424 c in a middle segment 428 can be comprised of both fibers and/or yarns comprising the low processing temperature polymeric composition and fibers and/or yarns comprising the high processing temperature polymeric composition, but in a different configuration/concentration as that which is found in textile zone 424 b and/or 424 d of the middle segment 428. Stated differently, various constructions techniques allow for combinations of fibers and/or yarns in given segments and textile zone by variations in the method of combining, including, attaching, depositing or applying the fibers and/or yarn (e.g., stitch selection) that allow for variations in fiber and/or yarn concentration at segment levels and/or textile zone levels.

The cross-section 418 of FIG. 4C includes the same type of general tubular knit structure discussed above with respect to the cross-sections 402 and 410 of FIGS. 4A and 4B, respectively. Accordingly, the cross-section 418 includes a top segment 426, a middle segment 428, and a bottom segment 430. The top segment 426, the middle segment 428, and the bottom segment 430 can include the same knit structures discussed above with reference to the top segment 404, the middle segment 406, and the bottom segment 408 of the cross-section 402 of FIG. 4A, respectively.

In the cross-section 418 of FIG. 4C, the portions 422 and 424 a include knit structures made with yarn that comprises the low processing temperature polymeric composition, while the portions 420, 424 d, and 424 c include knit structures made with yarn that comprises the high processing temperature polymeric composition. However, as provided above, it is contemplated that combinations of fibers and/or yarn based on differing stitch techniques can be implemented in the various portions to achieve a transition from one primary material to another primary material.

The portion 424 b includes the tubular knit structure made from yarn that comprises the high processing temperature polymeric composition; however, knit structures formed from the front and back needle beds (with yarn(s) comprising the high processing temperature polymeric composition) are connected via the float and tuck stitches (or an effective stitch comparable) from a yarn comprising the low processing temperature polymeric composition. This portion 424 b illustrates how, when melted and solidified, the low processing temperature polymeric composition can physically connect two outer knit layers together via a plaque or film of thermoformed material, once the textile 300 undergoes thermoforming. In such aspects, an article of wear having this type of tubular knit structure that has been thermoformed and connected via an integral thermoformed material would primarily include typical knit yarn layers on opposing outer surfaces of the textile that are connected together via a thermoformed film. Such a structure could be utilized to provide water-proofing/resistance or other weather proofing to an article of wear while still maintaining a typical knit article aesthetic and hand feel.

Like the cross-section 418 of FIG. 4C, the cross-section 432 of FIG. 4D includes a portion 436 that corresponds to the textile zone 302, and a portion 434 that corresponds to the textile zone 306 a. The portions 438 a, 438 b, 438 c, and 438 d correspond to the subzones 305 a, 305 b, 305 c, and 305 d, respectively, of the textile zone 304 a of the textile 300.

The top region 440, the middle region 442, and the bottom region 444 of the cross-section 432 of FIG. 4D can include the same knit structures discussed above with reference to the top segment 404, the middle segment 406, and the bottom segment 408 of the cross-section 402 of FIG. 4A, respectively, in order to provide the same type of general tubular structure.

The portions 434 and 438 d of the cross-section 432 of FIG. 4D include knit structures that include yarn that comprises the high processing temperature polymeric composition while the portions 436, 438 a, and 438 b include knit structures made with yarn that comprises the low processing temperature polymeric composition, in an exemplary aspect. However, as also provided above, it is contemplated that a primary, but not exclusive, material selection can be used. For example, in portion 438 b, the yarn comprising the high processing temperature polymeric composition can be present in the middle region 442 to aid in the transition of materials. The concentration of the yarn comprising the high processing temperature polymeric composition in portion 438 b can be less than that present in portion 438 c of the same middle region 442. For example, the portion 438 b can have at least 5 wt % less, 10 wt % less, or 25 wt % less yarn comprising the high processing temperature polymeric composition than is present in portion 438 c of the same middle region 442.

The portion 438 c includes the tubular structure with yarn that comprises the low processing temperature polymeric composition, which are connected via the float and tuck stitches from a yarn comprising the high processing temperature polymeric composition. In such aspects, upon thermoforming this portion 438 c can encapsulate the yarn comprising the high processing temperature polymeric composition in a plaque of the melted and cooled thermoformed material. In certain aspects, such a structure can provide some flexibility to an otherwise rigid thermoformed material.

For example, FIG. 4E depicts a cross-section 446 that is identical to the cross-section 432 of FIG. 4D with the exception that an anchor yarn 448 has been added to at least a portion of the regions that include the yarn comprising the low processing temperature polymeric composition. In certain aspects, the anchor yarn 448 can have any or all of the properties discussed above with respect to the anchor yarn 413 of FIG. 4B. For example, the anchor yarn can be incorporated into the textile using one or more of the knit structures depicted in FIGS. 5E and 5G-J.

As can be seen in FIG. 4E the anchor yarn 448 extends from the portion 450 of the cross-section 446, which corresponds to the textile zone 302, and into the portions 452 a and 452 b, which correspond to the subzones 305 a and 305 b of the textile zone 304 a. Further, in such aspects, FIG. 4E illustrates that yarn comprising the low processing temperature polymeric composition is also present (e.g., as a yarn having one or more of the knit structures present in FIGS. 5A and 5B) in at least the same portions of the textile as the anchor yarn 448. Thus, in certain aspects, the anchor yarn 448 can extend as a float stitch along at least two, at least three, at least four, or at least five adjacent loops of the yarn comprising the low processing temperature polymeric composition. Further in certain aspects, the anchor yarn 448 can extend as a float stitch along at least two, at least three, at least four, or at least five adjacent loops of the yarn comprising the low processing temperature polymeric composition and also can form at least a portion of a tuck stitch and/or a knit stitch with the yarn comprising the low processing temperature polymeric composition. In such aspects, between tuck stitches or knit stitches at least partly formed with yarn comprising the low processing temperature polymeric composition and the anchor yarn 448, the anchor yarn 448 can extend at least two, at least three, at least four, or at least five adjacent loops of the yarn comprising the low processing temperature polymeric composition. In the same or alternative aspects, the anchor yarn 448 can be stitched, e.g., tuck stitch or knit stitch, at loops spaced apart by needle count an amount of within 50% or within 25% of the gauge of a knit machine used to form at least a portion of the textile 300.

As discussed above, in one or more aspects, the anchor yarn 448 can extend from the textile zone 302 into the textile zone 304 a and toward the textile zone 306 a. In such aspects, the anchor yarn 448 can not extend from the textile zone 302 into the textile zone 304 a and toward the textile zone 306 a as far as a yarn comprising the low processing temperature polymeric composition extends into the zone 304 a and toward the textile zone 306 a, because there is less need to restrict flow during thermoforming and/or provide flexibility to the thermoformed material since the yarn comprising the high processing temperature polymeric composition from the zone 306 a is also present in textile zone 304 a.

For example, in the cross-section 446 of FIG. 4E, the anchor yarn extends from the portion 450 (corresponding to a portion of the textile zone 302) and into the portion 452 b (corresponding to the subzone 305 b of the textile 300). Further, the cross-section 446 illustrates that the top segment 456 and bottom segment 460 of the cross-section 446 show that yarn comprising the low processing temperature polymeric composition extends from the portion 450 and into the portion 452 c towards the portion 454 (corresponding to the textile zone 406 a), which is beyond the extension of the anchor yarn 448 in the same direction. However, in the middle segment 458, in portions 452 c and 452 d, the yarn comprising the high processing temperature polymeric composition is present, which can provide flexibility to the thermoformed textile and/or restrict flow during thermoforming.

As discussed above, in certain aspects, when the textile 300 is a knit textile, the cross-sections of the textile depicted in FIGS. 4A-4E are depicted with a top segment, bottom segment, and middle segment, where the top and bottom segments can form a tubular knit structure (and where tuck stitches or other connecting stitches present in the middle segment can also form part of the tubular or general knit structure) with a top and bottom knit layers. In such aspects, each of the top and bottom outer knit layers can include a plurality of interconnected courses.

Further, as can be seen in the textile 300 of FIG. 3, in the zone 304 a, the subzones 305 a-d have at least one staggered interface, e.g., staggered interface 306. The staggered interfaces, e.g., the staggered interface 306, provide a staggered or non-linear transition between subzones of the textile 300 along the width w of the textile. In such aspects, these staggered interfaces provide a more refined integrated transition, when the textile 300 is thermoformed, between the rigid area formed by the low processing temperature polymeric composition in the textile zone 302 and the flexible pliable area formed by the yarn comprising the high processing temperature polymeric composition in the textile zone 306 a. In aspects, this refined integrated transition provided at least in part by the staggered interfaces, can increase the durability or tear resistance of the thermoformed textile 300, as opposed to a similar textile having a linear abrupt transition between an integral rigid material and a flexible material.

In aspects where the textile 300 is a knit textile, the staggered interface 306 can depict how different courses of yarn on either the top or bottom outer knit layers can have different amounts of loops (or general stitch selection) of a yarn comprising the low processing temperature polymeric composition and/or a yarn comprising the high processing temperature polymeric composition. As the textile can have multiple layers (e.g., a top, middle, and bottom), the staggered interface can be addressed in any combination of the layers and is not limited to the surfaces exposed or depicted. Instead, as provided herein and as contemplated, a transition from a first primary material (e.g., fibers and/or yarn comprising the high processing temperature polymeric composition) to a second primary material (e.g., fibers and/or yarn comprising the low processing temperature polymeric composition) forming a textile, the transition can occur at a middle layer exclusively or in combination with one or more outer layers. It should be understood for the purposes of the following discussion of knit layers, it is assumed that, when the textile 300 of FIG. 3 is a knit textile, the view of the textile 300 depicts a top layer. Further, the same description equally applies to the bottom knit layer.

FIG. 6 schematically depicts one exemplary portion 600 of the top layer of the textile 300 showing a portion of a staggered interface 306. As can be seen in FIG. 6, the portion 600, a first course 602 of loops is interconnected to a second course 604 of loops. It should be understood that while only two interconnected courses are depicted in FIG. 6, more than two courses can be interconnected in the top knit layer of the textile 300. As used herein “interconnected,” when referencing interconnected courses, refers to how at least a portion of the loops in a first course of loops are tethered to at least a portion of the loops in a second course of loops. One exemplary aspect of interconnected courses is depicted in FIG. 6, where individual loops from the second course 604 are interlooped with individual loops from the first course 602. As used herein, “interlooped” refers to the how a loop from one course can wrap around a loop of another course such as in a knit stitch, and also refers to how one loop can have another segment of yarn pulled through the loop (or through the loop and around the yarn forming the loop) in order to form a second loop, as in a crochet process.

As can be seen in the portion 600 of the textile 300, both the first course 602 and the second course 604 include two types of yarns: a first yarn 606 that can comprise the high processing temperature polymeric composition, and a second yarn 608 that can comprise the low processing temperature polymeric composition. While only two courses are depicted in the portion 600, it should be understood that the top knit layer of the textile 300 can include any number of courses. In aspects, each of the courses present in the top knit layer of the textile 300 can include two or more types of yarn, as depicted in FIG. 6.

As can be seen in FIG. 6, each course, e.g., the first course 602 and the second course 604, can extend from the textile zone 302 to the textile zone 306 a (in aspects, each of the course can extend from the textile zone 306 a to the textile zone 306 b). In certain aspects, as can be seen in FIG. 6, the second yarn 608 in both the first course 602 and the second course 604 can extend from the textile zone 302 into the textile 304 a. In the same or alternative aspects, the first yarn 606 can extend from the textile zone 304 a into the textile zone 306 a. It should be understood that, while the schematic portion 600 of the textile 300 depicts each loop as only having a single yarn, more than one yarn can be present at one or more loops (e.g., another yarn can form a tuck stitch with the loops of the portion 600 of FIG. 6), as depicted in the cross-sections of FIGS. 4A-4E.

As discussed above, the portion 600 of the outer knit layer of the textile 300 illustrates at least a portion of the staggered interface 306. In certain aspects, the staggered interface 306 (and any other staggered interfaces) can be formed by the same type of yarn in multiple courses extending different distances from the one zone (or subzone) into the next zone or subzone. For example, as can be seen in FIG. 6, in the first course 602, the second yarn 608 extends from the textile zone 302 into the textile zone 304 a and towards the textile zone 306 a further than the second yarn extends from the textile zone 302 into the textile zone 304 a and towards the textile zone 306 a. In such aspects, the different distances of extension of the second yarn 608 into the textile zone 304 a results in different amounts of loops of the second yarn 608 in each of the first course 602 and the second course 604, which can change a concentration of yarn for a given zone/subzone. Thus, in such aspects, within the textile zone 304 a a loop of the second yarn 608 in the first course 602 can be interlooped with a loop of the second yarn 608 in the first course 602 at a first wale 608, while at a second wale 610 the second yarn 608 of the first course 602 can be interlooped to a loop of the first yarn 604 in the first course 602. In the same or alternative aspects, within the textile zone 304 a, the first yarn 604 in the first course 602 can be interlooped with the first yarn 604 in the second course 604 at a third wale 612.

In one or more aspects, a staggered interface, e.g., the staggered interface 306, can result in adjacent courses of the plurality of courses in the textile 300 having different numbers of loops of the yarn comprising the low processing temperature polymeric composition and of a yarn comprising the high processing temperature polymeric composition. For example, as can be seen in the portion 600 of the upper knit layer of the textile 300 depicted in FIG. 6, in at least a portion of the textile zone 304 a the first course 602 has a different number of loops of the first yarn 606, and/or of the second yarn 608, than the second course 604. Further, in the same or alternative aspects, within at least a portion of the textile zone 304 a, adjacent wales can have one or more loops of different yarns. For example, as illustrated in the portion 600 of the upper knit layer of the textile 300 in FIG. 6, the wale 610 includes loops of both the first yarn 606 and the second yarn 608, while the wale 612 includes loops of the first yarn 606.

As discussed above, the textiles described herein, which can include fibers and/or yarns comprising the low processing temperature polymeric composition, can be thermoformed to impart some structure of properties to the article of wear. Further, as discussed above, the thermoforming process can cause at least a portion of the low processing temperature polymeric composition present in the textile to melt or deform and subsequently solidify.

FIG. 7A schematically depicts a portion 700 of the textile zone 304 a of the upper knit layer of the textile 300 of FIG. 3 prior to a thermoforming process. The portion 700 includes a first course 702 and a second course 704 having a first yarn 708 that comprises the high processing temperature polymeric composition. The portion also includes a third course 706 of a second yarn 710 that comprises the low processing temperature polymeric composition. In such an aspect, the third course 706 of loops of the second yarn 710 can be interconnected, e.g., interlooped, to the first course 702 and the second course 707 having the first yarn 708.

FIG. 7B depicts the portion 700 after being exposed to a thermoforming process. As can be seen by comparing FIGS. 7A and 7B, the second yarn 710 that comprises the low processing temperature polymeric composition was thermoformed from a yarn material into a melted yarn component 712. In certain aspects, the heating step of the thermoforming process at least partly caused the low processing temperature polymeric composition in the second yarn 710 to melt and flow and then subsequently solidify by the completion of the thermoforming process into the melted yarn component 712.

In aspects, as can be seen in FIGS. 7A and 7B, the thermoforming process has also transformed at least a portion of the knit structure of the portion 700 of the upper knit layer of the textile 300 of FIG. 3. For example, the courses 702, 704, and 706 depicted in FIG. 7A have been transformed such that the portion 700 no longer includes interconnected courses of loops of a yarn comprising the low processing temperature polymeric composition and a yarn comprising the high processing temperature polymeric composition, at least partly due to the transformation of the yarn 710 in the second course 706 to the melted yarn component 712. As can be seen in FIG. 7B, although the thermoforming process can eliminate the interconnected loops in the portion 700 of the upper knit layer of the textile 300 of FIG. 3, the remaining course 702 and 704 can be connected by the melted yarn component 712. In such aspects, this portion 700 of upper knit layer of the textile 300 of FIG. 3 can fix the position of the courses 702 and 704 to one another, as opposed to when the courses 702 and 704 were interconnected via the course 706 prior thermoforming. Further, in such aspects, a top portion 714 of the loops of the first course 702 can still be free to interconnect with other courses of yarn allowing one to modulate the level of rigidity and/or three-dimensional forming provided by the textile zone 304 a.

FIG. 8 depicts a cross-section of the portion 700 of the upper knit layer of the textile 300 of FIG. 3 along the cut line 8 illustrated in FIG. 7B. As can be seen in FIG. 8, at least portion of the first yarn 708 can be encapsulated within the melted yarn component 712. Depending on the conditions used during the thermoforming process, the melted yarn component 712 can solidify into a film-like structure surrounding at least a portion of the loops of the first course 702 and the second course 704 of the first yarn 708 that comprises the high processing temperature polymeric composition.

As can be seen in the aspect depicted in FIGS. 7B and 8, the first yarn 708 that comprises the high processing temperature polymeric composition did not melt or deform after being exposed to the thermoforming process. Further, in certain aspects, the first yarn 708 can contain a dye 716 (depicted as the speckling within the first yarn 708) that does not leach out after being exposed to the thermoforming process. For example, as can be seen in FIGS. 7B and 8, there is no visible leaching of the dye 716 from the first yarn 708 into adjacent regions of the melted yarn component 712, e.g., the adjacent region 718. In certain aspects, at least about 80 wt %, at least about 90 wt %, at least about 95 wt %, or at least 99 wt % of the dye 716 remains within the first yarn 708 or within the thermoformed portion 700 of the upper knit layer of the textile 300 of FIG. 3. In the same or alternative aspects, upon thermoforming, there is no visible leaching of the dye into any additional materials associated with the final article of wear, which the portion 700 of upper knit layer of the textile 300 of FIG. 3 textile 300 is incorporated into.

FIGS. 9A and 9B depict an aspect where the portion 700 of the upper knit layer of the textile 300 of FIG. 3 is exposed to the thermoforming process but only results in the deforming of the low processing temperature polymeric composition in the second yarn 710 without eliminating at least a portion of the interconnected courses 702, 704, and 706 of FIG. 7A. As used herein, “deform” and “deforming” in the context of the thermoforming process of a knit textile refers to the alteration of the structure of the yarn such that the yarn does not melt and flow in such a manner as to substantially eliminate the knit structure of the textile (e.g., eliminate one or more interconnected loops or interlooped courses).

FIG. 9A depicts a cross-section of the portion 700 of the upper knit layer of the textile 300 of FIG. 3 along the cutline 9A-B prior to the thermoforming process, and FIG. 9B depicts the same cross-section after the thermoforming process. As can be seen in FIG. 9B, upon being exposed the thermoforming process, the second yarn 710 in the third course 706 has an altered yarn structure 710 a while the structure of the first yarn 708 has not been altered. In this aspect, the second yarn 710 in the third course 706 maintains the interlooping with the first course 702 and the second course 704 and the overall knit structure of the portion 700 of the upper knit layer of the textile 300 of FIG. 3.

In certain aspects, this altered yarn structure 710 a can result in a mechanical coupling or physical bonding of the second yarn 710 to another yarn, e.g., the first yarn 706, (or to another portion of the second yarn 710). In certain aspects, during the thermoforming process, the yarn 710 can have been exposed to a temperature above the glass transition temperature T_(g) of the low processing temperature polymeric composition but not above the melting temperature of the low processing temperature polymeric composition. In such aspects, when the second yarn 710 is exposed to such an elevated temperature, the second yarn can soften and become pliable but not melt, allowing the yarn to slightly mold around at least a portion of adjacent yarn, e.g., the first 706, and upon cooling this altered yarn structure can be mechanically locked in place to physically bond to the adjacent yarn.

FIGS. 10A-10C depict a portion 1000 of the textile zone 302 upper knit layer of the textile 300 of FIG. 3 before and after thermoforming. FIG. 10A depicts three courses 1010, 1012, 1014 of a yarn that includes the low processing temperature polymeric composition. FIG. 10A further depicts the present of an anchor yarn 1016 extending as a float stitch 1016 a and a tuck stitch 1016 b.

FIG. 10B depicts the same portion 1000 of the textile zone 302 upper knit layer of the textile 300 of FIG. 3 after being exposed to the thermoforming process. As can be seen in FIG. 10B, the interlooped courses 1010, 1012, and 1014 of the yarn have been transformed into a melted yarn component 1018. Further, as can be seen in FIG. 10B and FIG. 10C, which is a cross-section along the cutline 10C of FIG. 10B, the anchor yarn 1016 has maintained its yarn structure and is now encapsulated within the melted yarn component 1018. It should be understood that while in FIG. 10B, the anchor yarn 1016 is depicted as being encapsulated within the melted yarn component 1018, it is also contemplated that the anchor yarn 1016 can be at least partially embedded within the melted yarn component 1018 such that at least a portion of the anchor yarn 1016 is not fully covered in the melted yarn component 1018.

As discussed above, in certain aspects, the textiles described herein can include a knit textile, e.g., such as the portions of a knit textile depicted in FIGS. 4A-10C. A knit upper for an article of footwear is one exemplary knit textile. In such aspects, at least a portion of the knit upper of the article of footwear, and in some aspects substantially the entirety of the upper, can be formed of the knit textile. The knit textile can additionally or alternatively form another element of the article of footwear such as the midsole or ground-facing outsole for example. The knit textile can have a first side forming an inner surface of the upper (e.g., facing the void of the article of footwear) and a second side forming an outer surface of the upper. An upper including the knit textile can substantially surround the void so as to substantially encompass the foot of a person when the article of footwear is in use. The first side and the second side of the knit textile can exhibit different characteristics (e.g., the first side can provide abrasion resistance and comfort while the second side can be relatively rigid and provide water resistance).

In aspects, the knit textile can be formed as an integral one-piece element during a knitting process, such as a weft knitting process (e.g., with a flat knitting machine or circular knitting machine), a warp knitting process, or any other suitable knitting process. That is, the knitting process can substantially form the knit structure of the knit textile without the need for significant post-knitting processes or steps. Alternatively, two or more portions of the knit textile can be formed separately and then attached. In some embodiments, the knit textile can be shaped after the knitting process to form and retain the desired shape of the upper (for example, by using a foot-shaped last). The shaping process can include attaching the knit textile to another object (e.g., a strobel) and/or attaching one portion of the knitted component to another portion of the knitted component at a seam by sewing, by using an adhesive, or by another suitable attachment process.

Forming an upper with the knit textile can provide the upper with advantageous characteristics including, but not limited to, a particular degree of elasticity (for example, as expressed in terms of Young's modulus), breathability, bendability, strength, moisture absorption, weight, and abrasion resistance. These characteristics can be accomplished by selecting a particular single layer or multi-layer knit structure (e.g., a ribbed knit structure, a single jersey knit structure, or a double jersey knit structure), by varying the size and tension of the knit structure, by using one or more yarns formed of a particular material (e.g., a polyester material, a monofilament material, or an elastic material such as spandex), by selecting yarns of a particular size (e.g., denier), or a combination thereof.

The knit textile can also provide desirable aesthetic characteristics by incorporating yarns having different colors or other visual properties arranged in a particular pattern. The yarns and/or the knit structure of the knit textile can be varied at different locations such that the knitted component has two or more portions with different properties (e.g., a portion forming the throat area of the upper can be relatively elastic while another portion can be relatively inelastic). In some aspects, the knit textile can incorporate one or more materials with properties that change in response to a stimulus (e.g., temperature, moisture, electrical current, magnetic field, or light).

In some aspects, the knit textile can include one or more yarns or strands that are at least partially inlaid or otherwise inserted within the knit structure of the knit textile during or after the knitting process, herein referred to as “tensile strands.” The tensile strands can be substantially inelastic so as to have a substantially fixed length. The tensile strands can extend through a plurality of courses of the knit textile or through a passage within the knit textile and can limit the stretch of the knit textile in at least one direction. For example, the tensile strands can extend approximately from a biteline of the upper to a throat area of the upper to limit the stretch of the upper in the lateral direction. The tensile strands can form one or more lace apertures for receiving a lace and/or can extend around at least a portion of a lace aperture formed in the knit structure of the knit textile.

In alternative aspects, the textiles described herein can include non-woven textiles. The non-woven textiles described herein can be produced by any conventional methods, such as any conventional mechanical, chemical, or thermal methods for bonding the fibers together, including needle entangling and water entangling.

FIGS. 11A-11C depict an aspect where the textile 300 of FIG. 3 is a non-woven textile and undergoes the thermoforming process. FIG. 11A is a schematic depiction of a portion 1100 of the textile zone 304 a of the textile 300 of FIG. 3. As can be seen in FIG. 11A, the portion includes a first grouping 1110 of first fibers 1116 that comprise the high processing temperature polymeric composition, a second grouping 1112 of the first fibers 1116, and a third grouping 1114 of second fibers 1118 that comprise the low processing temperature polymeric composition. It should be understood that the portion 1100 of the textile 300 is schematic and the placing and spacing of the first fibers 1116 and the second fibers 1118 can be different in a textile.

While not depicted in FIGS. 11A-11C, in aspects where the textile 300 is a non-woven textile, one or more interfaces between the different portions of different fibers can also include one or more staggered interfaces, e.g., the staggered interface 306. In such aspects, the staggered interface 306 can depict how the transition between zones or subzones having different concentrations of fibers comprising the low processing temperature polymeric composition and/or fibers comprising the high processing temperature polymeric composition does not occur in a linear manner along the width w of the textile 300 of FIG. 3.

Returning now to FIGS. 11A-11C, and FIG. 11C in particular, in aspects where the thermoforming process causing the melting and flowing of the low processing temperature polymeric composition in the second fibers 1118, the second fibers 1118 have been transformed into a non-fiber material 1120, while the first fibers 1116 have not been transformed and so remain in fiber form. In such aspects, the non-fiber material 1120 can join together the first grouping 1110 of the first fibers 1116 with the second grouping 1112 of the first fibers 1116. FIG. 11C shows a cross-section along the cutline 11C, which shows how in certain aspects, at least a portion of the first fibers 1116 can be encapsulated within the non-fiber material 1120. In aspects, it is contemplated that at least a portion of the first fibers 1116 can be can be at least partly embedded within the non-fiber material 1120 such that the first fibers 1116 are not fully encapsulated by the non-fiber material 1120.

Although not depicted in the figures, in certain aspects, upon being exposed to the thermoforming process, the second fibers 1118 can not melt and flow but instead can deform and alter shape. This deformation of fibers or yarns is depicted in FIGS. 9A and 9B. Like the deformation of fibers or yarns discussed above with respect to FIGS. 9A and 9B, in certain aspects, the second fibers can deform and mold on another first or second fiber (or the same fiber) and mechanically couple or physically bond to that fiber.

Processes for Manufacturing

Certain conventional thermoforming processes include the selective thermoforming of only a portion of an article, e.g., by masking portions of the article not desired to be exposed to the thermoforming process, or using tooling which contacts or covers only a portion of an article. However, such conventional methods result in time and energy intensive manufacturing processes, as multiple steps are required to mask and unmask portions of the article before and after the thermoforming process, or multiple sets of tooling are required. Other conventional thermoforming processes include the thermoforming of article components prior to assembly into an article. This conventional process is also a time and resource intensive process, as multiple steps and machinery are required to individually form the article components prior to assembling the article. Moreover, an article formed from several individual components results in multiple seams where the individual components interface, thereby providing weaknesses in the article, less natural feel for a wearer, and/or actual discomfort or injury for a wearer.

The manufacturing processes disclosed herein solve one or more of the foregoing problems. The manufacturing processes disclosed herein utilize one or more of the shaped components, films, textiles, yarns and fibers disclosed herein, wherein the one or more shaped components, films, textiles, yarns and fibers comprises at least one low processing temperature polymeric composition as disclosed herein. The manufacturing processes disclosed herein also utilize one or more of the shaped components, films, textiles, yarns and fibers disclosed herein, wherein the one or more shaped components, films, textiles, yarns and fibers comprises at least one high processing temperature polymeric composition as disclosed herein. The disclosed manufacturing processes comprise a thermoforming step, in which the low processing temperature polymeric composition is softened or melted, which the high processing temperature polymeric composition is not melted or softened. The thermoforming is conducted over a temperature range below at least one of the following properties of the high processing temperature polymeric composition: (1) creep relaxation temperature (T_(cr)); (2) Vicat softening temperature (T_(vs)); (3) heat deflection temperature (T_(hd)); or (4) melting temperature (T_(m)). The thermoforming can be conducted over a temperature range below a creep relaxation temperature (T_(cr)) of the high processing temperature polymeric composition. The thermoforming can be conducted over a temperature range below a Vicat softening temperature (T_(cr)) of the high processing temperature polymeric composition. The thermoforming can be conducted over a temperature range below a heat deflection temperature (T_(hd)) of the high processing temperature polymeric composition. The thermoforming can be conducted over a temperature range below a melting temperature (T_(m)) of the high processing temperature polymeric composition.

For example, in certain aspects, as discussed further below, the specific and selective incorporation of a low processing temperature polymeric composition and a high processing temperature polymeric composition into an article provides a way to program structural features into an article that can be formed upon thermoforming. In some aspects, the article can comprise a textile comprising a low processing temperature polymeric composition and a high processing temperature polymeric composition, e.g., a textile comprising at least one plurality of fibers or yarn comprising a low processing temperature polymeric composition in at least a portion of the textile. In another aspect, the article can comprise a first shaped component, film, textile, yarn or plurality of fibers comprising the low processing temperature polymeric composition, and a second shaped component, film, textile, yarn or plurality of fibers comprising the high processing temperature polymeric composition, e.g., a knit upper for an article of footwear comprising the high processing temperature polymeric composition, and a film comprising the low processing temperature polymeric composition. In further aspects, the article can comprise an aggregation of components at least a portion of which comprise a low processing temperature polymeric composition and a high processing temperature polymeric composition, upon which the disclosed thermoforming process has been applied.

Since, in aspects, such structural features are built into the article depending upon the location in the article of the low processing temperature polymeric composition and the high processing temperature polymeric composition, upon thermoforming these structural features become integrated with each other, allowing for a more natural feel for the wearer or user. For example, a knit program for electronic knitting equipment can used to determine the location of structural features. However, as already noted, the manufacturing processes (and advantages associated with these processes) is not limited to the use of the textiles disclosed herein. For example, a process to form structural features in a disclosed article can utilize a film comprising a low processing temperature polymeric composition with a textile comprising a high processing temperature polymeric composition is also contemplated as a process to program structural features into a disclosed article. Alternatively, a process to effectively program structural features into a disclosed article can utilize a shaped component comprising a low processing temperature polymeric composition with a textile comprising a high processing temperature polymeric composition.

Additionally, this selective incorporation of the low processing temperature polymeric composition and the high processing temperature polymeric composition into an article provides for a streamlined manufacturing process. For example, in certain aspects, an entire article can be formed by arranging components and exposing the arranged components to a thermoforming process, where the components that include the low processing temperature polymeric composition melt, flow, and re-solidify into a more rigid structural feature, while the components that include the high processing temperature polymeric composition do not deform during the thermoforming process. In such aspects, this allows for the entire article to be exposed to the thermoforming process without the need to mask or protect areas that the manufacturer does not wish to melt, flow, and re-solidify, thereby resulting in a more time and energy efficient manufacturing process. Further, in some cases, use of the articles described herein in the manufacturing processes described herein also allows for several different structural or other advantageous features to be provided in the article without the need to combine individual components into the final article, since such features can be built into the article at the textile level using the low processing temperature polymeric composition and the high processing temperature polymeric composition.

In various aspects, the thermoforming process occurs at a temperature below which a yarn or fiber has been dyed (e.g., a temperature below with a yarn or fiber comprising the high processing temperature polymeric composition was dyed) so that such dye does not leach out of the yarn or fiber and into the surround low processing temperature polymeric composition during the thermoforming process. Thus, in order to form various textiles and articles described herein, the melting temperature of the low processing temperature polymeric composition in a first yarn or fiber is below a temperature used to dye a second yarn or fiber, such as a second yarn or fiber comprising the high processing temperature polymeric composition.

Further, the compositions having this range of melting temperature (i.e., a melting temperature below a temperature at which a second yarn or fiber comprising the high processing temperature polymeric composition was dyed) created another problem, in that such many of the low processing temperature polymeric compositions tested evaluated did not produce yarns suitable for use in commercial knitting equipment, as the yarns produced shrank significantly when exposed to the temperature under which commercial knitting equipment typically operates.

In particular examples, the low processing temperature polymeric compositions described herein have melting characteristics and acceptable levels of shrinkage when present in a yarn and used in commercial knitting equipment. For example, in certain aspects, the low processing temperature polymeric compositions can exhibit a melting temperature T_(m) that is 135° C. or less.

In certain aspects, thermoforming the articles and textiles described herein can be conducted over a range of temperatures which cause the low processing temperature polymeric composition to melt or deform (and subsequently solidify) while the high processing temperature polymeric composition does not melt and/or deform, thus maintaining the structure of the element comprising the high processing temperature polymeric composition, such as a yarn or fiber. In such aspects, this thermoforming process can result in a more rigid structural component (such as an outsole portion of a shoe) integrally connected to a less rigid portion of the article or textile, such as an upper portion of the shoe having a yarn or fiber that comprises the high processing temperature polymeric composition.

Accordingly, in one aspect, a process for manufacturing an article provided. The article can be a component of an article of footwear, a component of an article of apparel, or is a component of an article of sporting equipment.

The process also comprises placing at least a portion of the article on a molding surface. Further, the process includes, while the at least a portion of the article is on the molding surface, increasing a temperature of the entire article to a temperature that is above the melting temperature T_(m) of the low processing temperature polymeric composition and below at least one of: 1) the creep relaxation temperature T_(cr); 2) the heat deflection temperature T_(hd); or 3) the Vicat softening temperature T_(vs) of the high processing temperature polymeric composition.

Exemplary Pre-Thermoforming and Thermoforming Processes

As discussed above, in certain aspects, the articles and textiles described above, e.g., the textile 300 of FIG. 3, can form at least a portion of an article of wear, such as an article of footwear. In such aspects, the textile can form an upper for the article of footwear, where the upper includes a ground-facing outsole portion.

In certain aspects, the article or textile can be combined with additional materials in forming the upper for the article of footwear. For example, in one or more aspects, the textile can be combined or layered with one or more of an ankle collar lining, ankle collar foam, upper lining, or upper foam layer. In certain aspects, one or more of these additional materials can be secured to the textile, e.g., by knitting, stitching, or adhesion, prior to thermoforming the textile.

In certain aspects, to provide additional comfort and/or support to a wearer for an article of footwear formed at least partly by the textiles described herein, an internal support device or chassis can be provided. FIGS. 12 and 13 depict an article of footwear 1200 that includes a chassis 1210. The article of footwear 1200 includes a textile 1212 forming an upper 1214 having a ground-facing outsole portion 1216. In certain aspects, as can best be seen in FIG. 13, which depicts a cross-section of the article of footwear 1200, the chassis 1210 is positioned in the interior portion 1218 of the article of footwear 1200 and contacting an inner surface 1220 of the textile 1212. In certain aspects, the chassis 1210 can include a polymeric material such as a high processing temperature polymeric material, e.g., a polyether block amide, which has a melting or deforming temperature above the temperature range over which the thermoforming process is conducted, so that the polymeric material is capable of not melting or deforming during the thermoforming process described herein.

In various aspects, for a wearer's heel support, a heel counter 1222 can be positioned on the interior portion 1218 of the upper 1214, or on an exterior portion of the upper 1214, or can form a portion of the upper 1214. In aspects, like the chassis, 1210, the heel counter 1222 can include a polymeric material such as a high processing temperature polymeric material, e.g., a polyether block amide that is capable of not melting or deforming when exposed to the thermoforming process. In aspects, like the chassis, 1210, the heel counter 1222 can include portions formed of a low processing temperature polymeric composition in addition to portions formed of a high processing temperature polymeric composition

In certain aspects, a sockliner 1224 can be positioned on top of the chassis 1210 in the interior 1218 of the article of footwear 1200. In such aspects, the sockliner 1224 can include conventional sockliner materials, such as one or more layers of a foam or memory foam and a textile layer. It should be understood that while, a chassis 1210, heel counter 1222, and a sockliner 1224 are depicted as additional materials for forming the upper for the article of footwear, other materials could also be added, such as plates, toe caps, and/or structures along the sides.

In various aspects, the heel counter 1222 and the chassis 1210 can be positioned in the interior 1218 of the article of footwear 1200 prior to thermoforming. In certain aspects, the sockliner can be applied after the thermoforming process is completed.

In certain aspects, such as that depicted in FIG. 14, ground-engaging cleats 1410 can be applied to an article of footwear 1400. In aspects, the article of footwear 1400 can include the same features as the article of footwear 1200 described above with reference to FIGS. 12 and 13. As can be seen in FIG. 14, the ground-engaging cleats 1410 can be applied to the ground-facing outsole area 1412 of the article of footwear 1400 to provide increase stability and traction. In aspects, the ground-engaging cleats 1410 can be applied to the ground-facing outsole area 1412 after the thermoforming process is completed. In other aspects, the ground-engaging cleats 1410 can be applied to the ground-facing outsole area 1412 as part of the thermoforming process.

In various aspects, prior to thermoforming an article of footwear, the textile and any of the additional materials discussed above can be braided, woven, knitted or pre-formed into the general booty-type shape of an upper with a ground-facing outsole portion, such as that depicted in the upper 1500 of FIG. 15. In such aspects, the upper 1500 can also include a chassis or heel counter positioned on the inside 1510 of the upper 1500, such as the chassis 1210 and heel counter 1222 discussed above with respect to FIG. 12.

In order to prepare the upper 1500 for the thermoforming process, the upper 1500 is placed on a last 1520 such that the last 1520 enters the inside 1510 of the upper 1500. In certain aspects, the last 1520 can be formed of a polymeric material such as a high processing temperature polymer composition. In a particular aspect, the last 1520 can be formed of a polymeric material having a melting temperature T_(m) or a degradation temperature greater than 250° C. or greater than 300° C. such as, for example, a silicone polymer. The last 1520 can be made of other types of material as long as such a material would not be deformed or melt during the thermoforming process or otherwise adversely affect the thermoforming of the upper. FIG. 16 depicts the upper 1500 positioned on the last 1520. As can be seen in FIG. 16, the upper 1500 wraps around the last 1520 to cover a bottom portion 1522 of the last 1520, a forefoot portion 1524 of the last 1520, and a heel portion 1526 of the last 1520. In such aspects, the ground-facing outsole portion 1512 of the upper covers the bottom portion 1524 of the last 1520. Although the upper 1500 is illustrated in FIGS. 15 and 16 as having a sock-like structure which wraps around and covers the bottom portion 1522, the forefoot portion 1524, and the heel portion 1526 of the last 1520, in other aspects, the upper 1500 can only partially wrap around the last 1520. Similarly, in other aspects, the upper 1500 can cover only the bottom portion 1522 of the last 1520, only the forefoot portion 1524 of the last 1520, only the heel portion 1526 of the last 1520, or combinations thereof. In yet other aspects, the upper 1500 can cover only a portion of the bottom portion 1522 of the last 1520, a portion of the forefoot portion 1524 of the last 1520, a portion of the heel portion 1526 of the last 1520, or combinations thereof.

FIG. 17 shows a cross-section of the upper 1500 positioned on the last 1520 along the cutline 17. The cross-section 1700 reveals that the last 1500 contacts the inner surface 1540 of the upper 1500. The cross-section 1700 also reveals the two types of materials present in the upper 1500. For example, the cross-section 1700 reveals the three types of textile zones of the textile forming the upper 1500. As can be seen in FIG. 17, the textile zone 1710, which is associated with the ground-facing outsole portion 1512 of the upper, covers the bottom portion 1524 of the last 1520. In such aspects, when the upper is a knit textile forming a knitted upper, at least a portion of the yarn comprising the low processing temperature polymeric composition is covering at least a portion of the bottom portion 1524 of the last 1520.

Further, the textile zone 1714 covers the forefoot portion 1524 of the last 1520, while the textile zone 1712 covers the midfoot area 1528 of the last. In certain aspects, the textile zones 1710, 1712, and 1714 can have any or all of the properties discussed above with reference to the textile zones 302, 304 a, 306 a of FIG. 3, respectively.

In certain aspects, a first layer can be placed on a molding surface, such as a last, before the article, such as an article of footwear or component of an article of footwear. For example, a first layer, such as a liner, can be optionally placed over a molding surface, such as a last. For example, referring to FIG. 17 to further exemplify an aspect of a first layer that can be optionally placed on a molding surface, such as a last, before the article, a liner, can be placed over last 1520, such that a forefoot region of the liner covers the forefoot region 1524. Accordingly, an upper, comprising the textile zones 1710, 1712, and 1714, is then placed such it covers at least a portion of the liner. Thus, at least a portion of the yarn comprising the low processing temperature polymeric composition is covering at least a portion of the liner. It is understood that in certain aspects, the textile zones 1710, 1712, and 1714 can have any or all of the properties discussed above with reference to the textile zones 302, 304 a, 306 a of FIG. 3, respectively.

In further aspects, an outer layer can be optionally positioned on at least a portion of the article that is positioned on a molding surface and covering at least a portion of the article. The outer layer, such can be a film, can be optionally placed over at least a portion of an article, such as an upper, that is positioned on a molding surface, such as a last. For example, referring to FIG. 17 to further exemplify an aspect of an outer layer can be optionally placed over at least a portion of an upper that has been positioned on an last, such that the textile zone 1710, which is associated with the ground-facing outsole portion 1512 of the upper, covers the bottom portion 1524 of the last 1520. Accordingly, at least a portion the upper, comprising the textile zones 1710, 1712, and 1714, can be covered by at least a portion of the outer layer. Thus, at least a portion of the yarn comprising the low processing temperature polymeric composition is in contact with at least a portion of the outer layer. It is understood that in certain aspects, the textile zones 1710, 1712, and 1714 can have any or all of the properties discussed above with reference to the textile zones 302, 304 a, 306 a of FIG. 3, respectively. The outer layer can be utilized in conjunction with a first layer as described in the preceding paragraph.

In certain aspects, a shaped component, such as a heel counter or a toe cap, can be optionally placed on an outer surface 1530 of an upper 1500. Alternatively, a shaped component, such as a heel counter or a toe cap, can be optionally placed on an inner surface 1540 of an upper 1500. It is understood that the placement of a shaped component, whether an outer surface 1530 of an upper 1500 or an inner surface 1540 of an upper 1500, is completed before applying a protective sheath, a vacuum, or a protective sheath and a vacuum bag as described herein below.

In certain aspects, during the thermoforming process, the low processing temperature polymeric composition can melt and flow. In various aspects, it can be desirable to restrict the flow of the melted low processing temperature polymeric composition. In such aspects, a protective sheath can be applied over the upper positioned on a last. For example, as can be seen in FIGS. 18 and 19, a protective sheath 1800 is positioned over the upper 1500 positioned on the last 1520. In certain aspects, the protective sheath 1800 can be formed of a polymeric material such as a high processing temperature polymer composition. In a particular aspect, the protective sheath 1800 can be formed of an elastomeric polymeric material having a melting temperature T_(m) or a degradation temperature greater than 250° C. or greater than 300° C. such as, for example, a silicone polymer. The protective sheath 1800 can be made of other types of material as long as such a material would not be deformed or melt during the thermoforming process or otherwise adversely affect the thermoforming of the upper. In aspects, the protective sheath 1800 can apply a compressive force to the outer surface 1530 of the upper 1500, which can aid in restricting the flow of the melted low processing temperature polymeric composition. Further, in such aspects, a vacuum can be drawn on the combination of the last 1520, the upper 1500 positioned on the last, and the protective sheath positioned on the upper 1500. For example, a bag under vacuum can be compressed on the outside of the protective sheath 1800 to apply a compressive force to the protective sheath 1800 to ensure the sheath 1800 is in flush contact with the outer surface 1530 of the upper 1500. The vacuum bag is discussed in more detail below.

In certain aspects, the protective sheath 1800 can be utilized to provide a pattern or marking on the outer surface of the upper 1500. For example, the inner surface 1810 of the protective sheath 1800 can include markings or patterns, which during the thermoforming process can be embossed or imprinted on the outer surface 1530 of the upper 1500, due to the melting and cooling of the low processing temperature polymeric composition in the upper 1500 combined with a compressive force applied by the protective sheath 1800 (and optionally a vacuum bag) onto the upper 1500. In such aspects, since the protective sheath 1800, can cover the entire upper 1500 it is possible for the protective sheath 1800 to emboss or imprint a pattern onto any portion of the outer surface 1530 of the upper 1500 that includes the low processing temperature polymeric composition.

In certain aspects, it may be desirable to optionally use both a protective sheath and a vacuum bag together. In such aspects, a protective sheath can be applied over the upper positioned on a last. For example, as can be seen in FIGS. 18 and 19, a protective sheath 1800 is positioned over the upper 1500 positioned on the last 1520. As disclosed herein above, the protective sheath 1800 can be formed of an elastomeric polymeric material having a melting temperature T_(m) or a degradation temperature greater than 250° C. or greater than 300° C. such as, for example, a silicone polymer. Accordingly, the protective sheath 1800 is positioned on a last and inside of a vacuum bag 2010. As used herein, the term “vacuum bag” refers to any material that can compress onto the outer surface of an object. It is understood that the various methods of applying a compressive force to a protective sheath or a vacuum bag, as discussed in the present disclosure, can be used to apply a compressive force to both the protective sheath and vacuum bag as used together.

In certain aspects, use of the protective sheath 1800 alone and when used under vacuum can be effective in reducing the number of air bubbles which become trapped in the low processing temperature polymer material during the thermoforming process, as compared to an identical upper thermoformed under similar conditions except without the use of the protective sheath 1800.

In the aspects depicted in FIGS. 15-19, the last 1520 is formed of a rigid material. Further, in these aspects, when the last 1520 is made of a rigid material, the compressive force applied via the protective sheath 1800 (and/or the vacuum bag) creates a force or pressure differential between the inner 1540 and outer 1530 surfaces of the upper 1500 (since the rigid last 1520 at least partly resists this compressive force which results in the upper 1500 experiencing the compressive force). In such aspects, this pressure differential can at least partly provide the environment necessary to restrict the flow of the melted low processing temperature polymeric composition and/or provide embossing or patterning to the outer surface 1530 of the upper 1500.

In certain aspects, the upper 1500 can be positioned on the last 1520 when formed of a rigid material and the outer surface 1530 of the upper 1500 (with or without the protective sheath 1800) can be exposed to a pressure above a T_(m)ospheric pressure to create this pressure differential. In another aspect, the upper 1500 can be positioned on the last 1520 and a negative pressure can be applied between the inner surface 1540 of the upper 1500 and the last 1520 to compress the upper 1500 onto the rigid last 1520.

In aspects, the pressure differential across the inner 1540 and outer 1530 surfaces of the upper 1500 can also aid in forming the three-dimensional structure of the article of footwear during the thermoforming process. That is, in such aspects, as the low processing temperature polymeric composition is melting the melted material and the upper 1500 are forced up against the rigid last 1520, which when cooled, results in the upper 1500 taking on the shape of the last 1520.

In alternative aspects, this force or pressure differential between the inner 1540 and outer 1530 surfaces of the upper 1500 can be achieved in another manner. For example, in certain aspects, the last 1520 can be an expandable last 1520, which can apply an outward force to the inner surface 1540 of the upper 1500. In such aspects, to achieve the pressure differential, the outer surface 1530 of the upper 1500 can be contacting some type of material that will at least partly resist the outward force applied by the expanding of the last 1520.

As discussed above, a vacuum bag can be applied to the upper 1500 positioned on the last 1520, with or without the protective sheath 1800. FIG. 20A depicts the upper 1500 positioned on the last 1520 inside of a vacuum bag 2010. As used herein the term “vacuum bag” refers to any material that can compress onto the outer surface of an object.

In the aspect depicted in FIG. 20A, the vacuum bag 2010 can include a valve 2012 for reducing pressure inside the vacuum bag 2010. For example, the pressure can be reduced between the outer surface 1530 of the upper 1500 (or an outer surface of the protective sheath 1800 on the upper 1500) and the inside 2014 of the vacuum bag 2010, which will compress the vacuum bag onto the outer surface 1530 of the upper 1500 (or an outer surface of the protective sheath 1800 on the upper 1500). FIG. 20B depicts the vacuum bag 2010 compressed onto the outer surface 1530 of the upper 1500 (or an outer surface of the protective sheath 1800 on the upper 1500). As discussed above, the compression of the vacuum bag 2010 onto the upper 1500 can provide, at least partly, the pressure differential discussed above with reference to FIGS. 15-19.

FIG. 21 depicts a thermoforming system 2100. The thermoforming system 2100 of FIG. 21 can include the upper 1500 positioned on the last 1520 with a vacuum bag 2010 compressed onto the upper 1500, as discussed above with respect to FIGS. 20A and 20B.

As discussed above, the thermoforming process includes increasing the temperature of the textile material, e.g., the upper 1500, to a temperature that can cause at least a portion of the low processing temperature polymeric composition present in the upper 1500 to melt and flow, or to deform. Further, the thermoforming process includes the subsequent decreasing of the temperature of the upper 1500 to solidify the melted low processing temperature polymeric composition into the desired shape, such as an article of footwear.

The thermoforming system 2100 includes a heating zone 2110 that can be configured to heat the entire upper 1500. In aspects, the heating zone 2110 heats the entire upper 1500 to a temperature that is above the melting temperature T_(m) of the low processing temperature polymeric composition present in the upper 1500.

In various aspects, it is to be understood that although the heating used in thermoforming have been discussed specifically with regard to application with an upper 1500, this is only an exemplary aspect of heating and thermoforming for the disclosed articles and processes. That is, it is contemplated by the present disclosure that any of the disclosed heating methods used to provide a heating zone in the thermoforming systems and processes can be utilized to heat for thermoforming any disclosed article comprising a first shaped component, a first film, a first textile, a first yarn, or a first fiber and a second shaped component, a second film, a second textile, a second yarn, or a second fiber positioned on a molding surface, with the ensemble covered, at least in part, with a vacuum bag, a protective sheath, or a combination of a protective sheath and a vacuum, and then heat to a temperature of above the T_(m) of a low processing temperature composition. The first shaped component, the first film, the first textile, the first yarn, or the first fiber comprises the low processing temperature composition.

In aspects, heating the entire upper 1500 can provide for a more efficient streamlined thermoforming process. For example, because shaped component, films, textiles, fibers and/or yarns comprising the low processing temperature polymeric composition and the shaped components, films, textiles, fibers and/or yarns comprising the high processing temperature polymeric composition are selected and targeted to specific areas of the upper, it is not necessary to thermoform only a portion of the upper (such as, for example, by masking a portion of the upper or applying heat to only a portion of the upper), since the high processing temperature polymeric composition can be resistant to undergoing any deformation or melting under conditions that can thermoform the low processing temperature polymeric composition. However, optionally, additional thermal processing steps may be performed on the thermoformed article of the present disclosure. For example, one or more surfaces of a thermoformed article may be subjected to additional thermoforming processes, for example, to thermally attach cleats to a ground-facing surface of an article of footwear prepared using the thermoforming processes described herein.

As discussed above, it is desirable that the thermoforming process does not deform or alter the shaped components, films, textiles, fibers and/or yarn comprising the high processing temperature polymeric composition. In such aspects, the heating zone 2110 can heat the entire upper 1500 to a temperature that is below at least one of the creep relaxation temperature T_(cr), the heat deflection temperature T_(hd), or a Vicat softening temperature T_(vs) of the high processing temperature polymeric composition or of the fibers and/or yarn comprising the high processing temperature polymeric composition.

In one or more aspects, the heating zone 2110 can increase the temperature of the entire upper 1500 to a temperature of from about 90° C. to about 240° C. In aspects, the heating zone 2110 can increase the temperature of the entire upper 1500 to a temperature of from about 90° C. to about 200° C. In one aspect, the heating zone 2110 can increase the temperature of the entire upper 1500 to a temperature of from about 110° C. to about 180° C.

In certain aspects, the temperature of the entire upper 1500 can be increased for about 10 seconds to about 5 minutes. In aspects, the temperature of the entire upper 1500 can be increased for about 30 seconds to about 5 minutes. In one aspect, the temperature of the entire upper 1500 can be increased for about 30 seconds to about 3 minutes.

In one or more aspects, the heating zone 2110 can expose the entire upper 1500 to a temperature of from about 90° C. to about 240° C. In aspects, the heating zone 2110 can expose the entire upper 1500 to a temperature of from about 90° C. to about 200° C. In one aspect, the heating zone 2110 can expose the entire upper 1500 to a temperature of from about 110° C. to about 180° C.

In certain aspects, the entire upper 1500 can be exposed to one or more of the heating zone 2110 temperatures or ranges discussed above for about 10 seconds to about 5 minutes. In aspects, the entire upper 1500 can be exposed to one or more of the heating zone 2110 temperatures or ranges discussed above from about 30 seconds to about 5 minutes. In one aspect, the entire upper 1500 can be exposed to one or more of the heating zone 2110 temperatures or ranges discussed above from about 30 seconds to about 3 minutes.

In certain aspects, the heating zone 2110 can expose the entire upper 1500 to a pressure of about 50 kPa to about 300 kPa. In aspects, the heating zone 2110 can expose the entire upper 1500 to a pressure of about 50 kPa to about 250 kPa. In one aspect, the heating zone 2110 can expose the entire upper 1500 to a pressure of about from about 100 kPa to about 300 kPa.

In certain aspects, the entire upper 1500 can be exposed the heating zone 2110 under the above conditions multiple times in a row prior to undergoing the cooling step. For example, in some aspects, the entire upper 1500 can be exposed the heating zone 2110 under the above conditions 2-10 times in a row prior to undergoing the cooling step. In an alternative example, in some aspects, the entire upper 1500 can be exposed the heating zone 2110 under the above conditions twice in a row prior to undergoing the cooling step.

In various aspects, subsequent to increasing the temperature of the entire upper 1500, the temperature of the entire upper 1500 is decreased to a temperature below the melting temperature T_(m) of the low processing temperature polymeric composition for a duration of time sufficient for the low processing temperature polymeric composition to solidify. For example, the heating zone 2110 can be heated using a thermal energy source, including, but not limited to, conventional heaters, such as convection heating, a conventional oven, air-circulating oven or forced hot air oven, steam, targeted microwave heat, ultraviolet radiation, infrared heating, and combinations of any of the foregoing. The thermal energy source can further comprise a plurality of thermal energy sources such as a plurality of similar sources, e.g., a plurality of heating coils or infrared emitters. Alternatively, a plurality of thermal energy sources can comprise a plurality of one or more different thermal energy sources, e.g., a plurality of heating coils and a plurality of infrared emitters that can be used simultaneously or sequentially, or alternatively, used in a mode where only one of the plurality of thermal energy sources is used at any given time.

In some aspects, heating can be carried out such that heat is transferred from another material or object to an entire upper 1500. For example, a molding surface, such as a last, can itself be heated directly, e.g., via configuration as a resistive heating element. In an alternative aspect, a molding surface, such as a last, can be preheated to the desired temperature immediately prior to positioning an upper, a textile or an article thereon. In the foregoing aspects, the molding surface itself can act as a heating zone that transfers heat to an entire upper.

In some aspects, heating of heating zone can be carried out using radio-frequency heating, e.g., microwave radiation, such that the radio-frequency heats the compositions via interaction of a radio-frequency field with a composition, such as a low processing temperature composition, that is part of an upper, textile or article.

Further, in certain aspects, the entire upper 1500 can be exposed to the heating zone 2110 either by moving the entire upper 1500 into the heating zone 2110 or by the heating zone 2110 moving to where the upper 1500 is positioned and then moving away after the heating step. The movements of the upper 1500 and/or the heating zone 2110 can be automated or semi-automated using conventional conveyance systems.

In certain aspects, subsequent to heating the entire upper 1500, the entire upper 1500 is cooled to a temperature below the melting temperature T_(m) of the low processing temperature polymeric composition. In such aspects, the entire upper 1500 can be exposed to reduced temperatures in the cooling zone 2112 either by moving to the cooling zone 2112 or by the cooling zone 2112 moving the upper 1500. The cooling zone 2112 can expose the entire upper 1500 to a pressure of about 0 kPa.

In one or more aspects, the entire upper 1500, when in the cooling zone 2112, can be exposed to a temperature of about −25° C. to about 25° C. In aspects, the entire upper 1500, when in the cooling zone 2112, can be exposed to a temperature of about −10° C. to about 25° C. In one aspect, the entire upper 1500, when in the cooling zone 2112, can be exposed to a temperature of about from about −10° C. to about 10° C.

In certain aspects, the entire upper 1500 can be exposed to one or more of the cooling zone 2112 temperatures or ranges discussed above for about 10 seconds to about 5 minutes. In aspects, the entire upper 1500 can be exposed to one or more of the cooling zone 2112 temperatures or ranges discussed above for about 10 seconds to about 3 minutes. In one aspect, the entire upper 1500 can be exposed to one or more of the cooling zone 2112 temperatures or ranges discussed above for about 10 seconds to about 2.5 minutes.

In certain aspects, once the upper 1500 has been cooled as described above the vacuum bag 2010 and protective sheath 1800 can be removed. In such aspects, any additional components can now be applied to the upper 1500, such as the ground-engaging cleats 1410 of FIG. 14.

FIG. 22 depicts one exemplary process 2200 of manufacturing an upper for a shoe. The process 2200 can include the step 2210 of receiving an upper that includes a first material or component formed of a low processing temperature polymeric composition, and a second material or component formed of a high processing temperature polymeric composition.

In accordance with the exemplary process 2200 of FIG. 22 and of this disclosure generally, the low processing temperature polymeric composition can be present in the form of fibers (e.g., fibers that consist essentially of the low processing temperature polymeric composition). The low processing temperature polymeric composition can be present in the received upper in the form of a yarn (e.g., a yarn comprising the low processing temperature polymeric composition, a yarn formed entirely of fibers comprising the low processing temperature polymeric composition, a yarn formed partially of fibers comprising the low processing temperature polymeric composition). Additionally or alternatively, the low processing temperature polymeric composition can be present in the form of fibers that are not part of a yarn structure. For example, the fibers can comprise the low processing temperature polymeric composition, or can consist essentially of the low processing temperature polymeric composition. The low processing temperature polymeric composition also can be present in the form of a textile (including knit, braided, woven, and non-woven textiles), a film, a sheet, or a molded article, such as an injection molded article. The low processing temperature polymeric composition can also be present in the form of a foamed material.

Although certain aspects of the disclosure have been exemplified with particularity in relation to an article of footwear or an upper, the exemplified aspects can be generally understood to be used, within the scope of the disclosure, to be applicable to other disclosed aspects. For example, any disclosed low processing temperature composition can be utilized to form, fabricate, or manufacture a shaped component, a film, a textile, or other article, and used in the processes disclosed herein. Similarly, any disclosed high processing temperature composition can be utilized to form, fabricate, or manufacture a shaped component, a film, a textile, or other article, and used in the processes disclosed herein. Accordingly, any such a shaped component, a film, a textile, or other article comprising a low processing temperature composition can be optionally brought into contact with a shaped component, a film, a textile, or other article comprising a high processing temperature composition, and positioned on a molding surface. In some aspects, the molding surface can be a mold, a form, or a last. A protective sheath and/or a vacuum bag can be positioned thereon, a compressive force applied, and a heating zone provided thereto as described in the present disclosure.

In certain aspects, the second material formed from the high processing temperature polymeric composition can exhibit at least one of a creep relaxation temperature T_(cr), a heat deflection temperature T_(hd), or a Vicat softening temperature T_(vs) that is greater than the melting temperature T_(m) of the low processing temperature polymeric composition. The material formed from the low processing temperature polymeric composition can include any or all of the properties of the low processing temperature polymeric composition described above. The second material formed from the high processing temperature polymeric composition can include any or all of the properties of the high processing temperature polymeric composition described above. The second material formed from the high processing temperature polymeric composition can be present in the form of fibers (e.g., fibers that consist essentially of the high processing temperature polymeric composition). The high processing temperature polymeric composition can be present in the received upper in the form of a yarn (e.g., a yarn comprising the high processing temperature polymeric composition, a yarn formed entirely of fibers comprising the high processing temperature polymeric composition, a yarn formed partially of fibers comprising the high processing temperature polymeric composition). Additionally or alternatively, the high processing temperature polymeric composition can be present in the form of fibers that are not part of a yarn structure. For example, the fibers can comprise the high processing temperature polymeric composition, or can consist essentially of the high processing temperature polymeric composition. The high processing temperature polymeric composition also can be present in the form of a textile (including knit, braided, woven, and non-woven textiles), a film, a sheet, or a molded article, such as an injection molded article. The high processing temperature polymeric composition can also be present in the form of a foamed material. In certain aspects, the upper can include any or all of the properties of the upper 1500 described above with reference to FIGS. 15-21. Further, the upper can be formed using any of the textiles described above, such as the textile 300 of FIG. 3.

While the low processing temperature polymeric composition and the high processing temperature polymeric composition can be present as separate materials or components of the received upper (e.g., in separate fibers, yarns, textiles, films, etc.), they can also be present in the same component (e.g., yarns including fibers formed from the low processing temperature polymeric composition and separate fibers formed from the high processing temperature polymeric composition; textiles including yarns formed from the low processing temperature polymeric composition and separate yarns formed from the high processing temperature polymeric composition). In other words, in the received upper, the low processing temperature polymeric composition and the high processing temperature polymeric composition are present in materials or components which are separate and distinct from each other at least at the fiber level.

In one or more aspects, in a first portion of the upper, when the upper comprises a knit textile having a first yarn comprising a low processing temperature polymeric composition and a second yarn comprising a high processing temperature polymeric composition, at least one of the first yarn and the second yarn form a plurality of interconnected loops, such as the plurality of interconnected loops depicted in FIG. 6, 7A, or 9.

In the step 2220 of the process 2200, the upper is placed on a last, such as that depicted in FIGS. 15-17. In various aspects, the last can formed of a rigid material or can be an expandable last. Further, as described above, the upper can have a chassis, heel counter, or other components inserted into the upper prior to being placed on a last.

In the step 2230 of the process 2200, the temperature of the entire upper is increased, for example, heated, while on the last, to a temperature that is above the melting temperature T_(m) of the first yarn composition and below at least one of the creep relaxation temperature T_(cr), the heat deflection temperature T_(hd), or the Vicat softening temperature T_(vs) of the second yarn composition. In various aspects, the entire upper can be heated using the thermoforming system 2100 described above with respect to FIG. 21. The upper can be heated using any or all of the parameters described above with respect to the thermoforming system of FIG. 21.

In step 2240 of the process 2200, subsequent to heating the temperature of the entire upper is decreased to a temperature below a melting temperature T_(m) of the low processing temperature polymeric composition while the upper remains on the last. For example, the entire upper can be cooled while on the last to form the thermoformed upper. In various aspects, the entire upper can be cooled using the thermoforming system 2100 described above with respect to FIG. 21. The upper can be cooled using any or all of the parameters described above with respect to the thermoforming system of FIG. 21.

After thermoforming the received upper, as the thermoforming is conducted at a temperature at or greater than a melting temperature T_(m) of the low processing temperature polymeric composition but less than a creep relaxation temperature T_(cr), or a heat deflection temperature T_(hd), or a Vicat softening temperature T_(vs) of the high processing temperature polymeric composition, the second material or component (fiber, yarn, textile, sheet, molded article, etc.) comprising the high processing temperature polymeric composition retains its original physical structure (e.g., as a fiber, a yarn, a textile, etc.), while the first material or component comprising the low processing temperature polymeric composition has been deformed and its original structure has been modified, or has melted and solidified into a new physical structure.

FIG. 23 depicts one exemplary process 2300 of manufacturing an upper for a shoe. The process 2300 can include the step 2310 of receiving an upper that includes a first yarn and a second yarn, where the first yarn includes a low processing temperature polymeric composition and the second yarn includes a high processing temperature polymeric composition. The low processing temperature polymeric composition can include one or more first thermoplastic polymers, and the high processing temperature polymeric composition can include one or more second thermoplastic polymers. In aspects, the first and second thermoplastic polymers can include any or all of the parameters discussed above with respect to thermoplastic polymers. In certain aspects, the upper can include any or all of the properties of the upper 1500 described above with reference to FIGS. 15-21. Further, the upper can be formed using any of the textiles described above, such as the textile 300 of FIG. 3.

In certain aspects, the high processing temperature polymeric composition can exhibit at least one of a creep relaxation temperature T_(cr), a heat deflection temperature T_(hd), or a Vicat softening temperature T_(vs) that is greater than the melting temperature T_(m) of the low processing temperature polymeric composition. The low processing temperature polymeric composition can include any or all of the properties of the low processing temperature polymeric composition described above. The high processing temperature polymeric composition can include any or all of the properties of the high processing temperature polymeric composition described above. Further, the first and second yarn can exhibit any or all of the properties and parameters discussed above.

In one or more aspects, in a first portion of the upper, at least one of the first yarn and the second yarn form a plurality of interconnected loops, such as the plurality of interconnected loops depicted in FIG. 6, 7A, or 9.

In the step 2320 of the process 2300, the upper is placed on a last, such as that depicted in FIGS. 15-17. In various aspects, the last can formed of a rigid material or can be an expandable last. Further, as described above, the upper can have a chassis, heel counter, or other components inserted into the upper prior to being placed on a last.

In the step 2330 of the process 2300, the entire upper is heated, while on the last, to a temperature that is above the melting temperature T_(m) of the low processing temperature polymeric composition and below at least one of the creep relaxation temperature T_(cr), the heat deflection temperature T_(hd), or the Vicat softening temperature T_(vs) of the high processing temperature polymeric composition. In various aspects, the entire upper can be heated using the thermoforming system 2100 described above with respect to FIG. 21. The upper can be heated using any or all of the parameters described above with respect to the thermoforming system of FIG. 21.

In copolymers of this type, a α,ω-aminocarboxylic acid, the lactam and the dicarboxylic acid can be chosen from those described herein above and the diamine such as an aliphatic diamine containing from 6 to 12 atoms and can be arylic and/or saturated cyclic such as, but not limited to, hexamethylenediamine, piperazine, 1-aminoethylpiperazine, bisaminopropylpiperazine, tetramethylenediamine, octamethylene-diamine, decamethylenediamine, dodecamethylenediamine, 1,5-diaminohexane, 2,2,4-trimethyl-1,6-diaminohexane, diamine polyols, isophoronediamine (IPD), methylpentamethylenediamine (MPDM), bis(aminocyclohexyl)methane (BACM) and bis(3-methyl-4-aminocyclohexyl)methane (BMACM) can be used.

In various aspects, the constituents of the polyamide block and their proportion can be chosen in order to obtain a melting point of less than 150° C. and advantageously between 90° C. and 135° C. In a further aspect, the various constituents of the polyamide block and their proportion can be chosen in order to obtain a melting point of less than 150° C. and advantageously between 90° C. and 135° C.

In an aspect, the number average molar mass of the polyamide blocks can be from about 300 g/mol and about 15,000 g/mol, from about 500 g/mol and about 10,000 g/mol, from about 500 g/mol and about 6,000 g/mol, from about 500 g/mol to 5,000 g/mol, and from about 600 g/mol and about 5,000 g/mol. In a further aspect, the number average molecular weight of the polyether block can range from about 100 g/mol to about 6,000 g/mol, from about 400 g/mol to 3000 g/mol and from about 200 g/mol to about 3,000 g/mol. In a still further aspect, the polyether (PE) content (x) of the poly(ether block amide) polymer can be from about 0.05 to about 0.8 (i.e., from about 5 mol % to about 80 mol %). In a yet further aspect, the polyether blocks can be present from about 10 wt % to about 50 wt %, from about 20 wt % to about 40 wt %, and from about 30 wt % to about 40 wt %. The polyamide blocks can be present from about 50 wt % to about 90 wt %, from about 60 wt % to about 80 wt %, and from about 70 wt % to about 90 wt %.

In an aspect, the polyether blocks can contain units other than ethylene oxide units, such as, for example, propylene oxide or polytetrahydrofuran (which leads to polytetramethylene glycol sequences). It is also possible to use simultaneously PEG blocks, i.e. those consisting of ethylene oxide units, PPG blocks, i.e. those consisting of propylene oxide units, and P T_(m)G blocks, i.e. those consisting of tetramethylene glycol units, also known as polytetrahydrofuran. PPG or P T_(m)G blocks are advantageously used. The amount of polyether blocks in these copolymers containing polyamide and polyether blocks can be from about 10 wt % to about 50 wt % of the copolymer and from about 35 wt % to about 50 wt %.

The copolymers containing polyamide blocks and polyether blocks can be prepared by any means for attaching the polyamide blocks and the polyether blocks. In practice, two processes are essentially used, one being a 2-step process and the other a one-step process.

In the two-step process, the polyamide blocks having dicarboxylic chain ends are prepared first, and then, in a second step, these polyamide blocks are linked to the polyether blocks. The polyamide blocks having dicarboxylic chain ends are derived from the condensation of polyamide precursors in the presence of a chain-stopper dicarboxylic acid. If the polyamide precursors are only lactams or α,ω-aminocarboxylic acids, a dicarboxylic acid is added. If the precursors already comprise a dicarboxylic acid, this is used in excess with respect to the stoichiometry of the diamines. The reaction usually takes place between 180 and 300° C., preferably 200 to 290° C., and the pressure in the reactor is set between 5 and 30 bar and maintained for approximately 2 to 3 hours. The pressure in the reactor is slowly reduced to a T_(m)ospheric pressure and then the excess water is distilled off, for example for one or two hours.

Once the polyamide having carboxylic acid end groups has been prepared, the polyether, the polyol and a catalyst are then added. The total amount of polyether can be divided and added in one or more portions, as can the catalyst. In an aspect, the polyether is added first and the reaction of the OH end groups of the polyether and of the polyol with the COOH end groups of the polyamide starts, with the formation of ester linkages and the elimination of water. Water is removed as much as possible from the reaction mixture by distillation and then the catalyst is introduced in order to complete the linking of the polyamide blocks to the polyether blocks. This second step takes place with stirring, preferably under a vacuum of at least 50 mbar (5000 Pa) at a temperature such that the reactants and the copolymers obtained are in the molten state. By way of example, this temperature can be between 100 and 400° C. and usually between 200 and 250° C. The reaction is monitored by measuring the torque exerted by the polymer melt on the stirrer or by measuring the electric power consumed by the stirrer. The end of the reaction is determined by the value of the torque or of the target power. The catalyst is defined as being any product which promotes the linking of the polyamide blocks to the polyether blocks by esterification. Advantageously, the catalyst is a derivative of a metal (M) chosen from the group formed by titanium, zirconium and hafnium.

In an aspect, the derivative can be prepared from a tetraalkoxides consistent with the general formula M(OR)₄, in which M represents titanium, zirconium or hafnium and R, which can be identical or different, represents linear or branched alkyl radicals having from 1 to 24 carbon atoms.

In a further aspect, the catalyst can comprise a salt of the metal (M), particularly the salt of (M) and of an organic acid and the complex salts of the oxide of (M) and/or the hydroxide of (M) and an organic acid. In a still further aspect, the organic acid can be formic acid, acetic acid, propionic acid, butyric acid, valeric acid, caproic acid, caprylic acid, lauric acid, myristic acid, palmitic acid, stearic acid, oleic acid, linoleic acid, linolenic acid, cyclohexanecarboxylic acid, phenylacetic acid, benzoic acid, salicylic acid, oxalic acid, malonic acid, succinic acid, glutaric acid, adipic acid, maleic acid, fumaric acid, phthalic acid and crotonic acid. Acetic and propionic acids are particularly preferred. In some aspects, M is zirconium and such salts are called zirconyl salts, e.g., the commercially available product sold under the name zirconyl acetate.

In an aspect, the weight proportion of catalyst varies from about 0.01 to about 5% of the weight of the mixture of the dicarboxylic polyamide with the polyetherdiol and the polyol. In a further aspect, the weight proportion of catalyst varies from about 0.05 to about 2% of the weight of the mixture of the dicarboxylic polyamide with the polyetherdiol and the polyol.

In the one-step process, the polyamide precursors, the chain stopper and the polyether are blended together; what is then obtained is a polymer having essentially polyether blocks and polyamide blocks of very variable length, but also the various reactants that have reacted randomly, which are distributed randomly along the polymer chain. They are the same reactants and the same catalyst as in the two-step process described above. If the polyamide precursors are only lactams, it is advantageous to add a little water. The copolymer has essentially the same polyether blocks and the same polyamide blocks, but also a small portion of the various reactants that have reacted randomly, which are distributed randomly along the polymer chain. As in the first step of the two-step process described above, the reactor is closed and heated, with stirring. The pressure established is between 5 and 30 bar. When the pressure no longer changes, the reactor is put under reduced pressure while still maintaining vigorous stirring of the molten reactants. The reaction is monitored as previously in the case of the two-step process.

The proper ratio of polyamide to polyether blocks can be found in a single poly(ether block amide), or a blend of two or more different composition poly(ether block amide)s can be used with the proper average composition. In one aspect, it can be useful to blend a block copolymer having a high level of polyamide groups with a block copolymer having a higher level of polyether blocks, to produce a blend having an average level of polyether blocks of about 20 to 40 wt % of the total blend of poly(amid-block-ether) copolymers, and preferably about 30 to 35 wt %. In a further aspect, the copolymer comprises a blend of two different poly(ether-block-amide)s comprising at least one block copolymer having a level of polyether blocks below about 35 wt %, and a second poly(ether-block-amide) having at least about 45 wt % of polyether blocks.

Exemplary commercially available copolymers include, but are not limited to, those available under the tradenames of VESTAMID® (Evonik Industries); PELATAMID® (Arkema), e.g., product code H2694; PEBAX® (Arkema), e.g., product code “PEBAX MH1657” and “PEBAX MV1074”; PEBAX® RNEW (Arkema); GRILAMID® (EMS-Chemie AG), or also to other similar materials produced by various other suppliers.

In some examples, the thermoplastic polyamide is physically crosslinked through, e.g., nonpolar or polar interactions between the polyamide groups of the polymers. In examples where the thermoplastic polyamide is a thermoplastic copolyamide, the thermoplastic copolyamide can be physically crosslinked through interactions between the polyamide groups, an optionally by interactions between the copolymer groups. When the thermoplastic copolyamide is physically crosslinked thorough interactions between the polyamide groups, the polyamide segments can form the portion of the polymer referred to as the “hard segment”, and copolymer segments can form the portion of the polymer referred to as the “soft segment”. For example, when the thermoplastic copolyamide is a thermoplastic poly(ether-block-amide), the polyamide segments form the hard segment portion of the polymer, and polyether segments can form the soft segment portion of the polymer. Therefore, in some examples, the thermoplastic polymer can include a physically crosslinked polymeric network having one or more polymer chains with amide linkages.

In some aspects, the polyamide segment of the thermoplastic co-polyamide includes polyamide-11 or polyamide-12 and the polyether segment is a segment selected from the group consisting of polyethylene oxide, polypropylene oxide, and polytetramethylene oxide segments, and combinations thereof.

Optionally, the thermoplastic polyamide can be partially covalently crosslinked, as previously described herein. In such cases, it is to be understood that the degree of crosslinking present in the thermoplastic polyamide is such that, when it is thermally processed in the form of a yarn or fiber to form the articles of footwear of the present disclosure, the partially covalently crosslinked thermoplastic polyamide retains sufficient thermoplastic character that the partially covalently crosslinked thermoplastic polyamide is softened or melted during the processing and re-solidifies.

Thermoplastic Polyesters

In aspects, the thermoplastic polymers can comprise a thermoplastic polyester. The thermoplastic polyester can be formed by reaction of one or more carboxylic acids, or its ester-forming derivatives, with one or more bivalent or multivalent aliphatic, alicyclic, aromatic or araliphatic alcohols or a bisphenol. The thermoplastic polyester can be a polyester homopolymer having repeating polyester segments of the same chemical structure. Alternatively, the polyester can comprise a number of polyester segments having different polyester chemical structures (e.g., polyglycolic acid segments, polylactic acid segments, polycaprolactone segments, polyhydroxyalkanoate segments, polyhydroxybutyrate segments, etc.). The polyester segments having different chemical structure can be arranged randomly, or can be arranged as repeating blocks.

Exemplary carboxylic acids that that can be used to prepare a thermoplastic polyester include, but are not limited to, adipic acid, pimelic acid, suberic acid, azelaic acid, sebacic acid, nonane dicarboxylic acid, decane dicarboxylic acid, undecane dicarboxylic acid, terephthalic acid, isophthalic acid, alkyl-substituted or halogenated terephthalic acid, alkyl-substituted or halogenated isophthalic acid, nitro-terephthalic acid, 4,4′-diphenyl ether dicarboxylic acid, 4,4′-diphenyl thioether dicarboxylic acid, 4,4′-diphenyl sulfone-dicarboxylic acid, 4,4′-diphenyl alkylenedicarboxylic acid, naphthalene-2,6-dicarboxylic acid, cyclohexane-1,4-dicarboxylic acid and cyclohexane-1,3-dicarboxylic acid. Exemplary diols or phenols suitable for the preparation of the thermoplastic polyester include, but are not limited to, ethylene glycol, diethylene glycol, 1,3-propanediol, 1,4-butanediol, 1,6-hexanediol, 1,8-octanediol, 1,10-decanediol, 1,2-propanediol, 2,2-dimethyl-1,3-propanediol, 2,2,4-trimethylhexanediol, p-xylenediol, 1,4-cyclohexanediol, 1,4-cyclohexane dimethanol, and bis-phenol A.

In some aspects, the thermoplastic polyester is a polybutylene terephthalate (PBT), a polytrimethylene terephthalate, a polyhexamethylene terephthalate, a poly-1,4-dimethylcyclohexane terephthalate, a polyethylene terephthalate (PET), a polyethylene isophthalate (PEI), a polyarylate (PAR), a polybutylene naphthalate (PBN), a liquid crystal polyester, or a blend or mixture of two or more of the foregoing.

The thermoplastic polyester can be a co-polyester (i.e., a co-polymer including polyester segments and non-polyester segments). The co-polyester can be an aliphatic co-polyester (i.e., a co-polyester in which both the polyester segments and the non-polyester segments are aliphatic). Alternatively, the co-polyester can include aromatic segments. The polyester segments of the co-polyester can comprise or consist of polyglycolic acid segments, polylactic acid segments, polycaprolactone segments, polyhydroxyalkanoate segments, polyhydroxybutyrate segments, or any combination thereof. The polyester segments of the co-polyester can be arranged randomly, or can be arranged as repeating blocks.

For example, the thermoplastic polyester can be a block co-polyester having repeating blocks of polymeric units of the same chemical structure (segments) which are relatively harder (hard segments), and repeating blocks of polymeric segments which are relatively softer (soft segments). In block co-polyesters, including block co-polyesters having repeating hard segments and soft segments, physical crosslinks can be present within the blocks or between the blocks or both within and between the blocks. In a particular example, the thermoplastic material can comprise or consist essentially of an elastomeric thermoplastic co-polyester having repeating blocks of hard segments and repeating blocks of soft segments.

The non-polyester segments of the co-polyester can comprise or consist of polyether segments, polyamide segments, or both polyether segments and polyamide segments. The co-polyester can be a block co-polyester, or can be a random co-polyester. The thermoplastic copolyester can be formed from the polycodensation of a polyester oligomer or prepolymer with a second oligomer prepolymer to form a block copolyester. Optionally, the second prepolymer can be a hydrophilic prepolymer. For example, the co-polyester can be formed from the polycondensation of terephthalic acid or naphthalene dicarboxylic acid with ethylene glycol, 1,4-butanediol, or 1-3 propanediol. Examples of co-polyesters include polyethelene adipate, polybutylene succinate, poly(3-hydroxbutyrate-co-3-hydroxyvalerate), polyethylene terephthalate, polybutylene terephthalate, polytrimethylene terephthalate, polyethylene napthalate, and combinations thereof. In a particular example, the co-polyamide can comprise or consist of polyethylene terephthalate.

In some aspects, the thermoplastic polyester is a block copolymer comprising segments of one or more of polybutylene terephthalate (PBT), a polytrimethylene terephthalate, a polyhexamethylene terephthalate, a poly-1,4-dimethylcyclohexane terephthalate, a polyethylene terephthalate (PET), a polyethylene isophthalate (PEI), a polyarylate (PAR), a polybutylene naphthalate (PBN), and a liquid crystal polyester. For example, a suitable thermoplastic polyester that is a block copolymer can be a PET/PEI copolymer, a polybutylene terephthalate/tetraethylene glycol copolymer, a polyoxyalkylenediimide diacid/polybutylene terephthalate copolymer, or a blend or mixture of any of the foregoing.

In some aspects, the thermoplastic polyester is a biodegradable resin, for example, a copolymerized polyester in which poly(α-hydroxy acid) such as polyglycolic acid or polylactic acid is contained as principal repeating units.

The disclosed thermoplastic polyesters can be prepared by a variety of polycondensation methods known to the skilled artisan, such as a solvent polymerization or a melt polymerization process.

In some aspects, the thermoplastic polymers can comprise or consist essentially of a thermoplastic polyolefin.

In a further aspect, the thermoplastic polyolefin is a polymer comprising a polyethylene, an ethylene-α-olefin copolymer, an ethylene-propylene rubber (EPDM), a polybutene, a polyisobutylene, a poly-4-methylpent-1-ene, a polyisoprene, a polybutadiene, a ethylene-methacrylic acid copolymer, and an olefin elastomer such as a dynamically cross-linked polymer obtained from polypropylene (PP) and an ethylene-propylene rubber (EPDM), and blends or mixtures of the foregoing. Further exemplary thermoplastic polyolefins useful in the disclosed compositions, yarns, and fibers are polymers of cycloolefins such as cyclopentene or norbomene.

It is to be understood that polyethylene, which optionally can be crosslinked, is inclusive a variety of polyethylenes, including, but not limited to, low density polyethylene (LDPE), linear low density polyethylene (LLDPE), (VLDPE) and (ULDPE), medium density polyethylene (MDPE), high density polyethylene (HDPE), high density and high molecular weight polyethylene (HDPE-HMW), high density and ultrahigh molecular weight polyethylene (HDPE-UHMW), and blends or mixtures of any the foregoing polyethylenes. A polyethylene can also be a polyethylene copolymer derived from monomers of monolefins and diolefins copolymerized with a vinyl, acrylic acid, methacrylic acid, ethyl acrylate, vinyl alcohol, and/or vinyl acetate. Polyolefin copolymers comprising vinyl acetate-derived units can be a high vinyl acetate content copolymer, e.g., greater than about 50 wt % vinyl acetate-derived composition.

In some aspects, the thermoplastic polyolefin, as disclosed herein, can be formed through free radical, cationic, and/or anionic polymerization by methods well known to those skilled in the art (e.g., using a peroxide initiator, heat, and/or light). In a further aspect, the disclosed thermoplastic polyolefin can be prepared by radical polymerization under high pressure and at elevated temperature. Alternatively, the thermoplastic polyolefin can be prepared by catalytic polymerization using a catalyst that normally contains one or more metals from group IVb, Vb, VIb or VIII metals. The catalyst usually has one or more than one ligand, typically oxides, halides, alcoholates, esters, ethers, amines, alkyls, alkenyls and/or aryls that can be either p- or s-coordinated complexed with the group IVb, Vb, VIb or VIII metal. In various aspects, the metal complexes can be in the free form or fixed on substrates, typically on activated magnesium chloride, titanium(III) chloride, alumina or silicon oxide. It is understood that the metal catalysts can be soluble or insoluble in the polymerization medium. The catalysts can be used by themselves in the polymerization or further activators can be used, typically a group Ia, IIa and/or IIa metal alkyls, metal hydrides, metal alkyl halides, metal alkyl oxides or metal alkyloxanes. The activators can be modified conveniently with further ester, ether, amine or silyl ether groups.

Suitable thermoplastic polyolefins can be prepared by polymerization of monomers of monolefins and diolefins as described herein. Exemplary monomers that can be used to prepare disclosed thermoplastic polyolefin include, but are not limited to, ethylene, propylene, 1-butene, 1-pentene, 1-hexene, 2-methyl-1-propene, 3-methyl-1-pentene, 4-methyl-1-pentene, 5-methyl-1-hexene and mixtures thereof.

Suitable ethylene-α-olefin copolymers can be obtained by copolymerization of ethylene with an α-olefin such as propylene, butene-1, hexene-1, octene-1,4-methyl-1-pentene or the like having carbon numbers of 3 to 12.

Suitable dynamically cross-linked polymers can be obtained by cross-linking a rubber component as a soft segment while at the same time physically dispersing a hard segment such as PP and a soft segment such as EPDM by using a kneading machine such as a Banbbury mixer and a biaxial extruder.

In some aspects, the thermoplastic polyolefin can be a mixture of thermoplastic polyolefins, such as a mixture of two or more polyolefins disclosed herein above. For example, a suitable mixture of thermoplastic polyolefins can be a mixture of polypropylene with polyisobutylene, polypropylene with polyethylene (for example PP/HDPE, PP/LDPE) or mixtures of different types of polyethylene (for example LDPE/HDPE).

In some aspects, the thermoplastic polyolefin can be a copolymer of suitable monolefin monomers or a copolymer of a suitable monolefin monomer and a vinyl monomer. Exemplary thermoplastic polyolefin copolymers include, but are not limited to, ethylene/propylene copolymers, linear low density polyethylene (LLDPE) and mixtures thereof with low density polyethylene (LDPE), propylene/but-1-ene copolymers, propylene/isobutylene copolymers, ethylene/but-1-ene copolymers, ethylene/hexene copolymers, ethylene/methylpentene copolymers, ethylene/heptene copolymers, ethylene/octene copolymers, propylene/butadiene copolymers, isobutylene/isoprene copolymers, ethylene/alkyl acrylate copolymers, ethylene/alkyl methacrylate copolymers, ethylene/vinyl acetate copolymers and their copolymers with carbon monoxide or ethylene/acrylic acid copolymers and their salts (ionomers) as well as terpolymers of ethylene with propylene and a diene such as hexadiene, dicyclopentadiene or ethylidene-norbornene; and mixtures of such copolymers with one another and with polymers mentioned in 1) above, for example polypropylene/ethylene-propylene copolymers, LDPE/ethylene-vinyl acetate copolymers (EVA), LDPE/ethylene-acrylic acid copolymers (EAA), LLDPE/EVA, LLDPE/EAA and alternating or random polyalkylene/carbon monoxide copolymers and mixtures thereof with other polymers, for example polyamides.

In some aspects, the thermoplastic polyolefin can be a polypropylene homopolymer, a polypropylene copolymers, a polypropylene random copolymer, a polypropylene block copolymer, a polyethylene homopolymer, a polyethylene random copolymer, a polyethylene block copolymer, a low density polyethylene (LDPE), a linear low density polyethylene (LLDPE), a medium density polyethylene, a high density polyethylene (HDPE), or blends or mixtures of one or more of the preceding polymers.

In some aspects, the polyolefin is a polypropylene. The term “polypropylene,” as used herein, is intended to encompass any polymeric composition comprising propylene monomers, either alone or in mixture or copolymer with other randomly selected and oriented polyolefins, dienes, or other monomers (such as ethylene, butylene, and the like). Such a term also encompasses any different configuration and arrangement of the constituent monomers (such as atactic, syndiotactic, isotactic, and the like). Thus, the term as applied to fibers is intended to encompass actual long strands, tapes, threads, and the like, of drawn polymer. The polypropylene can be of any standard melt flow (by testing); however, standard fiber grade polypropylene resins possess ranges of Melt Flow Indices between about 1 and 1000.

In some aspects, the polyolefin is a polyethylene. The term “polyethylene,” as used herein, is intended to encompass any polymeric composition comprising ethylene monomers, either alone or in mixture or copolymer with other randomly selected and oriented polyolefins, dienes, or other monomers (such as propylene, butylene, and the like). Such a term also encompasses any different configuration and arrangement of the constituent monomers (such as atactic, syndiotactic, isotactic, and the like). Thus, the term as applied to fibers is intended to encompass actual long strands, tapes, threads, and the like, of drawn polymer. The polyethylene can be of any standard melt flow (by testing); however, standard fiber grade polyethylene resins possess ranges of Melt Flow Indices between about 1 and 1000.

Additives

In some aspects, a disclosed thermoplastic polymer, fiber, filament, yarn, or fabric can further comprise an additive. The additive can be incorporated directly into a fiber, filament, yarn, or fabric, or alternatively, applied thereto. Additives that can be used in the disclosed thermoplastic polymers, fibers, filaments, yarns, or fabrics include, but are not limited to, dyes, pigments, colorants, ultraviolet light absorbers, hindered amine light stabilizers, antioxidants, processing aids or agents, plasticizers, lubricants, emulsifiers, pigments, dyes, optical brighteners, rheology additives, catalysts, flow-control agents, slip agents, crosslinking agents, crosslinking boosters, halogen scavengers, smoke inhibitors, flameproofing agents, antistatic agents, fillers, or mixtures of two or more of the foregoing. When used, an additive can be present in an amount of from about 0.01 wt % to about 10 wt %, about 0.025 wt % to about 5 wt %, or about 0.1 wt % to 3 wt %, where the wt % is based upon the sum of the material components in the thermoplastic composition, fiber, filament, yarn, or fabric.

Individual components can be mixed together with the other components of the thermoplastic composition in a continuous mixer or a batch mixer, e.g., in an intermeshing rotor mixer, such as an Intermix mixer, a twin screw extruder, in a tangential rotor mixer such as a Banbury mixer, using a two-roll mill, or some combinations of these to make a composition comprising a thermoplastic polymer and an additive. The mixer can blend the components together via a single step or multiple steps, and can mix the components via dispersive mixing or distributive mixing to form the resulting thermoplastic composition. This step is often referred to as “compounding.”

In some aspects, the additive is an antioxidant such as ascorbic acid, an alkylated monophenol, an alkylthiomethylphenol, a hydroquinone or alkylated hydroquinone, a tocopherol, a hydroxylated thiodiphenyl ether, an alkylidenebisphenol, a benzyl compound, a hydroxylated malonate, an aromatic hydroxybenzl compound, a triazine compound, a benzylphosphonate, an acylaminophenol, an ester of β-(3,5-di-tert-butyl-4-hydroxyphenyl)propionic acid with mono- or polyhydric alcohols, an ester of β-(5-tert-butyl-4-hydroxy-3-methylphenyl)propionic acid with mono- or polyhydric alcohols, an ester of β-(3,5-dicyclohexyl-4-hydroxyphenyl)propionic acid with mono- or polyhydric alcohols, an ester of 3,5-di-tert-butyl-4-hydroxyphenyl acetic acid with mono- or polyhydric alcohols, an amide of β-(3,5-di-tert-butyl-4-hydromhenyl)propionic acid, an aminic antioxidant, or mixtures of two or more of the foregoing.

In a further aspect, the disclosed thermoplastic composition can comprise between about 0.01 wt % and about 3 wt % relative to the weight of the composition.

All technical and scientific terms used herein, unless defined otherwise, have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. It will be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the specification and relevant art and should not be interpreted in an idealized or overly formal sense unless expressly defined herein.

The terms “comprises,” “comprising,” “including,” and “having,” are inclusive and therefore specify the presence of features, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, steps, operations, elements, components, and/or groups thereof.

As used in the specification and the appended claims, the singular forms “a,” “an” and “the” include plural referents unless the context clearly dictates otherwise. Thus, for example, reference to “a low processing temperature polymeric composition,” “a high processing temperature polymeric composition,” or “a knit upper,” including, but not limited to, two or more such low processing temperature polymeric compositions, low processing temperature polymeric compositions, or knit uppers, and the like.

As used herein, the term “and/or” includes any and all combinations of one or more of the associated listed items.

The terms first, second, third, etc. can be used herein to describe various elements, components, regions, layers and/or sections. These elements, components, regions, layers and/or sections should not be limited by these terms. These terms can be only used to distinguish one element, component, region, layer or section from another region, layer or section. Terms such as “first,” “second,” and other numerical terms do not imply a sequence or order unless clearly indicated by the context. Thus, a first element, component, region, layer or section discussed below could be termed a second element, component, region, layer or section without departing from the teachings of the example configurations.

As used herein, the modifiers “upper,” “lower,” “top,” “bottom,” “upward,” “downward,” “vertical,” “horizontal,” “longitudinal,” “transverse,” “front,” “back” etc., unless otherwise defined or made clear from the disclosure, are relative terms meant to place the various structures or orientations of the structures of the article of footwear in the context of an article of footwear worn by a user standing on a flat, horizontal surface.

It should be noted that ratios, concentrations, amounts, and other numerical data can be expressed herein in a range format. Where the stated range includes one or both of the limits, ranges excluding either or both of those included limits are also included in the disclosure, e.g. the phrase “x to y” includes the range from ‘x’ to ‘y’ as well as the range greater than ‘x’ and less than ‘y’. The range can also be expressed as an upper limit, e.g. ‘about x, y, z, or less’ and should be interpreted to include the specific ranges of ‘about x’, ‘about y’, and ‘about z’ as well as the ranges of ‘less than x’, less than y’, and ‘less than z’. Likewise, the phrase ‘about x, y, z, or greater’ should be interpreted to include the specific ranges of ‘about x’, ‘about y’, and ‘about z’ as well as the ranges of ‘greater than x’, greater than y’, and ‘greater than z’. In addition, the phrase “about ‘x’ to ‘y’”, where ‘x’ and ‘y’ are numerical values, includes “about ‘x’ to about ‘y’”. It is to be understood that such a range format is used for convenience and brevity, and thus, should be interpreted in a flexible manner to include not only the numerical values explicitly recited as the limits of the range, but also to include all the individual numerical values or sub-ranges encompassed within that range as if each numerical value and sub-range is explicitly recited. To illustrate, a numerical range of “about 0.1% to 5%” should be interpreted to include not only the explicitly recited values of about 0.1% to about 5%, but also include individual values (e.g., 1%, 2%, 3%, and 4%) and the sub-ranges (e.g., 0.5%, 1.1%, 2.4%, 3.2%, and 4.4%) within the indicated range.

As used herein, the terms “about,” “approximate,” “at or about,” and “substantially” mean that the amount or value in question can be the exact value or a value that provides equivalent results or effects as recited in the claims or taught herein. That is, it is understood that amounts, sizes, formulations, parameters, and other quantities and characteristics are not and need not be exact, but can be approximate and/or larger or smaller, as desired, reflecting tolerances, conversion factors, rounding off, measurement error and the like, and other factors known to those of skill in the art such that equivalent results or effects are obtained. In some circumstances, the value that provides equivalent results or effects cannot be reasonably determined. In such cases, it is generally understood, as used herein, that “about” and “at or about” mean the nominal value indicated±10% variation unless otherwise indicated or inferred. In general, an amount, size, formulation, parameter or other quantity or characteristic is “about,” “approximate,” or “at or about” whether or not expressly stated to be such. It is understood that where “about,” “approximate,” or “at or about” is used before a quantitative value, the parameter also includes the specific quantitative value itself, unless specifically stated otherwise.

Reference to “a” chemical compound” refers to one or more molecules of the chemical compound, rather than being limited to a single molecule of the chemical compound. Furthermore, the one or more molecules can or can not be identical, so long as they fall under the category of the chemical compound. Thus, for example, “a polyamide” is interpreted to include one or more polymer molecules of the polyamide, where the polymer molecules can or can not be identical (e.g., different molecular weights and/or isomers).

The terms “at least one” and “one or more of” an element are used interchangeably, and have the same meaning that includes a single element and a plurality of the elements, and can also be represented by the suffix “(s)” at the end of the element. For example, “at least one polyamide”, “one or more polyamides”, and “polyamide(s)” can be used interchangeably and have the same meaning.

As used herein, the terms “optional” or “optionally” means that the subsequently described component, event or circumstance can or cannot occur, and that the description includes instances where said component, event or circumstance occurs and instances where it does not.

The term “receiving”, such as for “receiving an upper for an article of footwear”, when recited in the claims, is not intended to require any particular delivery or receipt of the received item. Rather, the term “receiving” is merely used to recite items that will be referred to in subsequent elements of the claim(s), for purposes of clarity and ease of readability.

As used herein the terms “weight percent,” “wt %,” and “wt %,” which can be used interchangeably, indicate the percent by weight of a given component based on the total weight of the composition, unless otherwise specified. That is, unless otherwise specified, all wt % values are based on the total weight of the composition. It should be understood that the sum of wt % values for all components in a disclosed composition or formulation are equal to 100.

Compounds are described using standard nomenclature. For example, any position not substituted by any indicated group is understood to have its valence filled by a bond as indicated, or a hydrogen atom. A dash (“—”) that is not between two letters or symbols is used to indicate a point of attachment for a substituent. For example, —CHO is attached through carbon of the carbonyl group. Unless defined otherwise, technical and scientific terms used herein have the same meaning as is commonly understood by one of skill in the art to which this invention belongs.

Unless otherwise specified, temperatures referred to herein are determined at standard a T_(m)ospheric pressure (i.e., 1 a T_(m)).

Property Analysis and Characterization Procedures

Evaluation of various properties and characteristics of the part and support materials described herein are by various testing procedures as described herein below.

Method to Determine the Creep Relation Temperature T_(cr).

The creep relation temperature T_(cr) is determined according to the exemplary techniques described in U.S. Pat. No. 5,866,058. The creep relaxation temperature T_(cr) is calculated to be the temperature at which the stress relaxation modulus of the tested material is 10% relative to the stress relaxation modulus of the tested material at the solidification temperature of the material, where the stress relaxation modulus is measured according to AS T_(m) E328-02. The solidification temperature is defined as the temperature at which there is little to no change in the stress relaxation modulus or little to no creep about 300 seconds after a stress is applied to a test material, which can be observed by plotting the stress relaxation modulus (in Pa) as a function of temperature (in ° C.).

Method to Determine the Vicat Softening Temperature T_(vs).

The Vicat softening temperature T_(vs) is be determined according to the test method detailed in AS T_(m) D1525-09 Standard Test Method for Vicat Softening Temperature of Plastics, preferably using Load A and Rate A. Briefly, the Vicat softening temperature is the temperature at which a flat-ended needle penetrates the specimen to the depth of 1 mm under a specific load. The temperature reflects the point of softening expected when a material is used in an elevated temperature application. It is taken as the temperature at which the specimen is penetrated to a depth of 1 mm by a flat-ended needle with a 1 mm² circular or square cross-section. For the Vicat A test, a load of 10 N is used, whereas for the Vicat B test, the load is 50 N. The test involves placing a test specimen in the testing apparatus so that the penetrating needle rests on its surface at least 1 mm from the edge. A load is applied to the specimen per the requirements of the Vicat A or Vicate B test. The specimen is then lowered into an oil bath at 23° C. The bath is raised at a rate of 50° C. or 120° C. per hour until the needle penetrates 1 mm. The test specimen must be between 3 and 6.5 mm thick and at least 10 mm in width and length. No more than three layers can be stacked to achieve minimum thickness.

Method to Determine the Heat DeflectionTemperature T_(hd).

The heat deflection temperature T_(hd) is be determined according to the test method detailed in AS T_(m) D64816 Standard Test Method for Deflection Temperature of Plastics Under Flexural Load in the Edgewise Position, using a 0.455 MPa applied stress. Briefly, the heat deflection temperature is the temperature at which a polymer or plastic sample deforms under a specified load. This property of a given plastic material is applied in many aspects of product design, engineering, and manufacture of products using thermoplastic components.

The present disclosure is more particularly described in the following examples that are intended as illustrations only, since numerous modifications and variations within the scope of the present disclosure will be apparent to those skilled in the art.

Example 1: Evaluation of Commercially Available Polymeric Materials for Use as Components of the Low Processing Temperature Polymeric Composition

In this example, twenty-five commercially available polymers were evaluated for their suitability as components of the low processing temperature polymeric composition. Samples of the polymers were evaluated in yarn and/or resin form to determine melting temperature T_(m), the number of cycles under the cold Ross flex (CRF) test, shrinkage in yarn form, and physical appearance after thermoforming. The results of this testing regimen are provided in Table 1 below.

While most of these commercially available materials had a melting temperature T_(m) within the desired range of less than about 125° C., the vast majority of the materials did not have the ideal balance of properties making them suitable for use in articles of footwear and apparel. For example, many of the materials had a yellow tint or were not transparent then thermoformed. Some of the materials, when extruded to form yarns, produced yarns with unacceptably high levels of shrinkage. Also, many of the materials became somewhat brittle under cold conditions and so were unable to withstand over 150,000 cycles of testing using the cold Ross flex test method, making the materials undesirable for some footwear applications.

For applications where it is unacceptable for the materials to become brittle under cold conditions, the Platamid H 2694/Pebax 4023 SA from Arkema was determined to be the one polymer tested that passed the Cold Ross flex (CRF) test at the desired level. This material exhibited all the other favorable polymeric properties desired for use in the low processing temperature polymeric composition described herein, such as a favorable melting temperature T_(m), and remaining clear when thermoformed.

Although the present disclosure has been described with reference to preferred aspects, workers skilled in the art will recognize that changes can be made in form and detail without departing from the spirit and scope of the disclosure.
